Hyperbolic Crochet

I love the idea that some fancy mathematical ideas can best be explained with a crocheted piece of fabric - hyperbolic planes. Here's a video that explains the idea, an interview and here the paper.

Plus, it makes a great bathroom sponge/scrubby :-) 

How to make it

If you want to crochet such a sponge, it's really easy to do: you only need some leftover cotton yarn and the appropriate crochet hook.

Do a magic ring with 6 single crochet stitches.

After that continue to crochet 2 sc into each single crochet (i.e. doubling the number of stitches every round) ... until it's big enough or you run out of yarn.

Enjoy!

Chair Cover

Upcycle your old blankets by cutting them into strips and knit a comfortable chair cover ... to sit a bit warmer on cool spring days.

I used an old fitted sheet (i.e. elastic material) and cut it in a spiral (as described here), except that I didn't tear the material, but used scissors. Afterwards I stretched the material a bit (as you do when making t-shirt yarn) while I wound it up into a big ball.

This chair cover is knitted along the lines of Frankie Brown's Ten Stitch Blanket pattern. However, it's not worked as a spiral.



I used 25mm needles and cut up sheets as yarn, but I guess T-shirt yarn will work fine, as well.

Here's how I did it:

Provisionally cast on 10 stitches,
Row 1: sl1 k9
Row 2: sl1 k8 w+t
Row 3: sl1 k to end
Row 4: sl1 k7 w+t
Row 5: sl1 k to end
Row 6: sl1 k6 w+t
Row 7: sl1 k to end
Row 8: sl1 k5 w+t
Row 9: sl1 k to end
Row 10: sl1 k4 w+t
Row 11: sl1 k to end
Row 12: sl1 k3 w+t
Row 13: sl1 k to end
Row 14: sl1 k2 w+t
Row 15: sl1 k to end
Row 16: sl1 k1 w+t
Row 17: sl1 k to end
Row 18: sl1 w+t
Row 19: k1
Row 20: sl1 k1 (picking up the wrapped stitch)
Row 21: sl1 k to end
Row 22: sl1 k2 (picking up the wrapped stitch)
Row 23: sl1 k to end
Row 24: sl1 k3 (picking up the wrapped stitch)
Row 25: sl1 k to end
Row 26: sl1 k4 (picking up the wrapped stitch)
Row 27: sl1 k to end
Row 28: sl1 k5 (picking up the wrapped stitch)
Row 29: sl1 k to end
Row 30: sl1 k6 (picking up the wrapped stitch)
Row 31: sl1 k to end
Row 32: sl1 k7 (picking up the wrapped stitch)
Row 33: sl1 k to end
Row 34: sl1 k8 (picking up the wrapped stitch)
Row 35: sl1 k to end
Row 36: sl1 k7 (picking up the wrapped stitch)
Row 37: sl1 k to end

Repeat Rows 1 to 37 a total of 3 times, then knit rows 1 to 36.
Graft ends together in garter stitch, i.e.

• setup: Front purl, back purl.
• front needle: knit slip, purl leave.
• back needle: knit slip, purl leave.

Mixed Wave Cowl - The First 5 Sections

I finally got round to knitting another cowl and taking photos of the process.
So, in the hope that this might help people who try to knit the cowl but at first cannot imagine how it will add up, here are photos of the first 5 sections. The marker around which a section has just been added, is pointed out with a red dot.

The first section is a left leaning section - knitted around the current marker 3.

 The second section is a right-leaning section - knitted around the current marker 5.

The third section is a left-leaning edge section - knitted around the marker that was number 6 when the five-section-sequence was started, but is now the fifth marker. Please note also, that a new marker (left of the marker with the red dot) has been put on the needle.

The forth section is a right-leaning edge section - knitted around the first marker on the needle.

The fifth section is a left-leaning section - knitted around the only marker that hadn't been used in this five-section-sequence.

The above photo shows a summary - above the markers it is written which section was knitted around it. You can see that all markers have been used while knitting five sections.

Please note,

• the new marker has been put on the needle because there were more than 10 stitches between the edge marker and the last pattern marker as well as 
• that the marker that was the first (when the five-section-sequence began) has been remove because it had reached the edge marker.

So cute

Short Wave Mitts (DK Version)

I knitted this DK version of the Short Wave Mitts to match a cowl I had made earlier - pinching the idea of inversing the colours from another knitter on Ravelry.

Materials:

• a total about 45 grams of DK weight yarn  (in two colours)
• 4.5 mm dpns

Here are the modifications to the original pattern:

Thumb panel:

• CO7 in MC
• do increase (to widen thumb panel) in rows 16 and 26
• do thumb increases in rows 32, 34, 36, 38 - move 11 sts to scrap yarn in row 40
• do decrease (to narrow thumb panel) in row 47
• BO thumb panel in row 58

Main Part:

• Pick up 30 sts from side => 31 sts on needles
• When first knitting a row down the side: k3 pm k8 pm k8pm k8 pm k4 (to mark the beginnings and endings of sections - the sections are 8 sts wide).
• Knit MC rows in stockinette stitch (i.e. k on RS, p on WS)
• There are only 4 down sections and 4 up sections

Thumb:

• for thumb pick up 3 sts from above gusset
• knit 4 rounds of garter stitch (i.e k 1 round, p 1 round) and BO

Variations on the Hitchhiker Theme

This scarf is based on the Hitchhiker pattern by Martina Behm - with some short row waves added.

To create the waves pattern, I used the technique described in the Mixed Waves Cowl pattern, i.e. dividing the width of your knitting into sections of the same length and filling them out with short rows in a random manner. As the scarf gets wider, it is also necessary to make the sections wider as you go along - I started with sections of 10 stitches and increasing them gradually ended up with a width of 20 stitches per section.

Mixed Wave Cowl

Knit yourself a warm winter cowl with a fascinating graphic pattern. Easily adaptable to either fit snugly around your neck or long enough to wind around twice.

This cowl is knitted flat and in a rhomboid shape - beginning and end are grafted when finishing. The wavy design is created by stacks of short rows interspersed with full garter stitch rows of a contrasting colour. A regular edging is added by knitting 3 stitches on each side on the RS and slipping them on the WS.

Before starting to knit, the general idea how to stack short rows should be understood – I have tried to explain my thoughts and I think it is advisable to read the explanations first … or just give it a try and use the example given in this blog post and read the theory section afterwards - or not at all.

My Experience with Short Rows

When I started using short rows, I first created a rectangle with very neatly stacked short rows (Short Wave Mitts),  then I made it more „organic“ knitting the same sections but in a different order (Mixed Wave Mitts) – only afterwards I figured out how to include the tilt (i.e. creating the rhomboid shape). So the two mitt patterns lead up to the cowl pattern you're reading right now. If you start with this pattern without any experience in short row stacks, the explanation might seem complicated – it is. I'm sorry, but that's how my mind works. If you have ideas for explaining it better or easier to understand, let me know and I will gladly include it or link to it.

A PDF-File of this pattern is available, too. This PDF includes the example mentioned above.
(Edit: 03.10.2021: updated PDF pattern link - somehow google seems to have changed the links on GoogleDrive so the old links weren't working anymore)

Materials

This is the amount I used for a small cowl that fits once around my neck.

• ~25 grams of DK weight yarn in neutral colour (NC, white in the photo)
• ~30 grams of DK weight yarn in colour 1 (C1, dark purple in the photo)
• ~30 grams of DK weight yarn in colour 2 (C2, light purple in the photo)
• 3.5 mm needles
• 8 stitch markers
• (2 edge markers and 6 markers for the
• waves pattern)
• tapestry needle

General Construction

The pictures below show how the cowl is generally construced. The rhomboid shape is created by increasing (with kfb) one stitch on one side every two rows and while decreasing at the same rate (with ssk) on the other side. In the end the shorter edges are grafted together.

Short Rows

The following paragraphs explains how the knitter should proceed to build the cowl from sections of short rows, to shape the piece as suggested and to get a smooth and consistent fabric. 

The pattern is made up of sections that are constructed of short rows, i.e. rows with 10 stitches on one side of your knitting and 8 stitches on the other side. To mark where the sections begin and end 6 „pattern markers“ are used – these are placed with a distance of 10 stitches inbetween. There are be left leaning sections (10 stitches on RS and 8 stitches on WS, called L1 to L6) and right leaning sections (8 stitches on RS and 10 stitches on WS, called R1 to R6).

At its highest point, a section is made up of 7 garter stitch ridges.
In a set-up row, markers are placed – there are edge markers and pattern markers. The 2 edge markers mark the borders between the 3 edge stitches on each side and the 60 stitches that make up the wave pattern. 6 pattern markers are placed at a fixed distance of 10 stitches between each other. The pattern markers are refered to a marker 1 to 6 (always numbered from 1 to 6 from right to left when viewed from the RS at any given time) throughout this pattern. Their behaviour will be discussed below.

The picture on the left shows possible sections. Each section has a central marker (marker X) and is placed between the two mar­kers around that central marker (marker X-1 and marker X+1). E.g. for both R3 and L3 marker 3 is the central marker and they have their highest stack at that central marker (marker 3), R3 starts at marker 4 and ends at marker 2; whereas L3 starts at marker 2 and ends at marker 4. (When a section X has been knitted its central marker will be called „used“. E.g. after knitting a left-leaning section L3 – its central marker (marker 3) will be considered as „used“.) The section is highest at its central marker.

There are mid sections (i.e. sections where the short row stack does not reach an edge, e.g. L2 or R4 in the picture above) and edge sections (i.e. sections where the short row stack reaches one of the edges, e.g. L1 or R6 in the picture above).

• Left leaning sections (all knitted in colour C1) start with the complete knit row on RS, the short row part (i.e. wrapping and turning) starts on WS; to make them lean to the left, on RS you knit 2 stitches over the the last wrapped stitch (10 stitches in the pattern) and on the WS you knit until 2 stitches before the last wrapped stitch (8 stitches in the pattern) before you do a w+t.

• Right leaning sections (all knitted in colour C2) start with the short row part on RS and end with the complete knit row on WS. Here, you knit until two stitches before the last wrapped stitch (8 stitches) on the RS and two stitches over the last wrapped stitch (10 stitches) on the WS.

• Left leaning and right leaning sections are knitted alternately

• Two rows (or one garter stitch ridge) knitted in a neutral colour (called NC) are placed inbetween the sections – to outline the wave pattern.

While knitting the piece the knitter must keep track of two things

1. that the number of stitches stays the same (66 stitches) to keep the fabric at a consistent width and
2. that the number of rows below each stitch is roughly the same – that way the fabric stays consistent and does not get bumpy

First 1) will be discussed, i.e. how to keep the number of stitches.

• Knitting NC rows is will not change the number of stitches, the ssk at the beginning of the row is balanced by the kfb at the end.
• Similarly, knitting a mid section will not affect the number of stitches since there is only one ssk at the beginning – balanced out by an kfb at the end.
• However, after an edge section is knitted, the number of of stitches will have (temporarily) been increased or decreased by 6 stitches. E.g., when a section at the decreasing edge has been knitted, only one kfb (at the increasing edge) was knitted, but 7 ssk's at the decreasing edge; the total number of stitches has been reduced by 6.  This must be balanced out by knitting a section at the other edge, i.e. after knitting a section at the decreasing edge, a section at the increasing edge should be knitted (and vice versa).

Now for b), i.e. how to make sure that there is an equal number of rows below each stitch.

When the knitter has knitted the very first section (say a mid section), the knitted piece is  something slim on the edges with a bump in the middle. This bump is around the central marker of the section that has just been knitted.  The next section – if knitted around a different central marker – will make up another bump. If these bumps are distributed evenly, the result after a few sections will be a consistent piece of knitting (i.e. with an even height or with the same number of garter stitch ridges below all stitches).
To achieve this even distribution the knitter has to make sure of the following:

• Choose a next section without a bump under its central marker.
• Distribute the number of edge sections and mid sections with a 2 to 3 ratio, i.e. when having knitted 3 mid sections, the next sections should be 2 edge sections; or – put differently – 2 sections out of 5 should be edge sections (one on each side).
• Ideally, for each five sections knitted five different markers should be used as central markers, so that the upper edge is smooth and that below each stitch is the same amount of rows.

The following paragraphs will explain the section selection process in more detail.

But first it must be discussed how the markers shift position: As explained above, when first casting on several markers will be placed: 2 edge markers (3 stitches from each side edge) and 6 pattern markers (with 10 sts inbetween) that will show where to start and end the sections.

• Throughout the pattern the edge markers stay in place while the pattern markers shift towards the decreasing edge – when decreasing by one stitch (ssk) on one side just after slipping the edge marker the distance between the decreasing edge and the pattern markers is reduced by one stitch. From the point of view of the uppermost row, it seems as if the pattern markers travel towards the decreasing edge.

• When a patten marker reaches the edge marker (decreasing side), it can be removed  – similarly, when there are more than ten stitches between the edge marker on the increasing side and the next pattern marker, a new marker must be placed ten stitches away from the next pattern marker. So when marker 1 on the decreasing edge is removed, the former marker 2 becomes the new marker 1 etc. – and when a new marker is placed at the increasing edge, it becomes the new marker 6. In summary, while the markers are shifted, they change their names/numbers.

Returning to the topic of choosing the next section: Once the knitter has knit a section around a marker, this section will (at least temporarily) show up as a bump within the fabric – correspondingly, sections with central markers that haven't been used for the last few sections will show up as holes or dents. The next sections should be knitted into a dent, i.e. knitted around  markers that haven't been „used“ as central markers recently. Therefore, markers that have already been used (i.e. are central markers for a section that has just been knitted) must be remembered. For example, if the knitter has just knitted L3 (left leaning section 3, which has its highest point at the current marker 3), this marker should be not to be used again within the next 4 or 5 sections.

When the markers travel (or are shifted), the structure of „used“ and not yet „used“ sections travels with them. Therefore, it is important that not the marker number should be remembered (they change as explained above), but the physical marker around which the section was knitted.

After a while it will become obvious which sections have already been knitted (i.e. which markers have already been „used“) and which should be knitted. Until that time the knitter needs to remember which sections have already been knitted, i.e. which central markers have been used.

Selecting the next sections may also require a certain amount of forward planning, keeping in mind that markers that are currently in the middle of the piece (and therefore markers for a mid section) may soon be markers for a section at the decreasing edge.
The picture  shows an example how the the first 6 sections can be arranged. But there are other choices as well.

Shaping the rhomboid and giving it a nice edge

• Each RS row is decreased on the right hand side and increased by one on the left hand side, this means it starts with k3 (slip edge marker) ssk and ends with kfb (slip edge marker) k3
• Each WS row (except the set-up row) starts with sl3 wyif and ends with sl3 wyif
• The RS k3s and WS sl3s wyif will draw the 3 edge stitches partly to the WS (see picture) - giving you a neat edge that my even hide the stranded yarn. They have got nothing to do with the waves pattern or the tilt.

Furthermore

• remember to strand your yarn - especially when knitting the decreasing edge sections and
• when you encounter a wrapped stitch, pick it up.
