I have pledged myself to make one square a day this month as my charity project for the month. As my stamina for crochet still runs out fairly fast - I've done comparatively little of it and it uses different movements to my usual knitting - I am sticking to the one a day to save doing myself an injury, already it's getting easier to do. To avoid having to sew in hundreds of ends when changing colours I am using Lucy from Attic 24's handy tutorial on crocheting the ends in as you go, which I highly recommend, it's not at all difficult.
So far my squares look rather Christmassy in colour, tomorrow I think I'll dig out some more colours and go for a bit more variety. Get crocheting and bring some more colour into the world!
