Tychus is a hat pattern by Brooke T. Higgins that is available for free via Ravelry or directly on knitty.com. Currently, there are more than 1600 projects listed for this pattern on Ravelry. It is knitted sideways with a short-row construction.
I didn't keep to the pattern, but made a few modifications - especially since I had started with yarn of a different weight. Here's what I did differently:
- I started with a provisional CO and ended by grafting in garter stitch, because wanted the hat to look seamless.
- I did a (provisional) cast on of 56 stitches (more than the original pattern), due to the yarn I used.
- I only worked the first halves of the wedges as described in the original pattern - and then I started again. In the end I knitted seven half-wedges to get the hat circumference that I wanted.
- In the original pattern a half-wedge consists of 8 ridges of short rows. Since I had thinner yarn, I did 12 ridges per half-wedge. (In fact, during a first attempt, I did 16 short rows per half-wedge - ending up with a piece of the right circumference, that was far too pointy. So, I had saved myself the work of knitting a swatch by knitting a bigger swatch ... as usual :/ ).
