Not that I'm ignoring colour! Here are my fourth hexigons for the Rowan CAL. These spirals were a blast to crochet - you just go around and around and around and only two ends to have to weave in.
I love the pattern so much that I've started a rug with some very bright Boodles yarn I found on sale (I've put the green hexi in the middle for scale). I'm using a 10mm crochet hook for this one and I can only do a bit at a time because your shoulders do start to hurt yanking this yarn through. It's going to be a very happy, spring-looking rug however so a little pain is worth it. Hooray for Bank Holiday weekend in the UK; I plan on lots of knitting/crochet and maybe even a bit of weaving time!
