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!

Crochet Dress

Seen in a shop window in Barcelona. I didn't look for a price tag ... ;-)

Buttercup

My Buttercup sweater (pattern by Heidi Kirmeier - available at Ravelry). I used some lovely Kaléido yarn - bought at La Droguerie in Paris.

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.
