PS for anyone like me who has always wanted but failed to crochet, Meet me at Mikes has a series of posts about how to crochet. There are so far 10 parts of the series, taking you right through from the very start to making a granny square.
This will be the very next craft thing I try, the posts look really good and I've wanted to crochet for ages. It's apparently easy, but my feeble previous attempts have all looked like a ball of yarn that's been attacked by a cat.
Try, try and try again.
