It's going to be a very free range affair. There's a facebook group (here) and a hashtag for Instagram (#thecrochetsockcal) so we can all share our progress and chat about our socks, there's also an official start date (Friday 24th June) but there are no particular rules, join in whenever you like. Just grab one of the patterns, some sock yarn and a hook, get crocheting and share your progress.
The patterns are available singly now as PDF downloads and the full collection is available as a download too and you can also purchase a printed copy on etsy.
Any 4ply sock yarn should do the trick, I'd generally say use something with a little nylon if possible and steer clear of cotton. The majority of the patterns use a 3.5mm hook, some also require a smaller hook for the ribbing, but obviously the size you need will mostly depend on your gauge. Hook details can be found on the ravelry page for each pattern.
There will be prizes! I have recently ventured into dyeing yarn so will be offering up a couple of skiens of my hand dyed sock yarn, plus some stitch markers and crochet hooks. I will share pictures once I have all prizes finalised, but to get you tempted here's a shot of some yarn I dyed especially to giveaway. I'll also set an end date for the prizes, though there's no deadline to finish the socks and you won't need to have finished for a chance to win.
We start officially tomorrow, but feel free to grab some yarn and get checking your gauge today if you like :)
I'm going to be using some lovely yarn from Burrow and Soar and I think I'm making the Winter Wonder socks.
