I like this apple one - it's cute. There are patterns for making a variety of cozies from chicks to a basket of violets.
I haven't actually had a go making any of these. That's partly because my knitting is not great and I can't follow knitting instructions, and I can only do one type of stitch. Having flicked through this book I'd say you need to be able to follow knitting instructions and do multiple stitches - it's not for beginners.
It is cute though and I have one to give away to one of you lucky lot. All you need to do to enter is leave a comment telling me what else you could use an egg cozy for. I like runny eggs so have no need for something to keep my eggs warm but I'm intrigued what other uses could exist.
So leave a comment and I'll pick my favourite. My choice is final.
**Edit: Forgot to say that this giveaway ends on Friday 24th August at 11pm.
