You can buy the pattern as part of the Cowl city ebook (4 cowl patterns for 4 euros).

This is a very flexible pattern - there is a sizing table with 3 sizes and 4 yarn weights (12 stitch counts), but you can also adjust it for other sizes.

It has worked well with all of the yarns tried so far.

knitting 1-2-3, 1-2-3 is very relaxing - apparently the same rhythm as walzing.

Errata - stitch count for bulky double loop should be 156.

Rounds 4-6: should be to last 4 sts, p3, k1
Rounds 7-9: should be to last 5 sts, p3, k2.

Many thanks to the testers for their fabulous knits:
