Leah day has a great website and hundreds of patterns of fmq.....I like the idea of different patterns for each block, but the problem with that is, it takes lots and lots of practice to get good at one pattern, one square just won't do it.....I would suggest picking a couple different patterns that you can alternate between the squares.....I am working on feathers now (sooo not as easy at it looks).....even just simple wavy lines takes practice to get consistent sizes.....whatever you choose, have fun with it and do your best not to get frustrated!
