I began making them this weekend. I've made all these little squares and they'll go on the cards. It didn't take nearly as long as I thought, mainly because I prepared well - I got all the stuff together and it all co-ordinated, so I could just put them together very easily a few at a time. Now I just need to make a load more and stick 'em on cards. They should hit the shops (well, shop) within a couple of weeks.
