It is all about personal preference. I am lucky to have about five tubs of fabric and a large bag of scraps that I am in the process of cutting into squares , strips etc. I have however put myself on a fabric buying ban. I have enough fabric to keep me going for a good few years. On monday I cut up a huge box of jeans to make two good size denim quilts. I have a big pile of shirts that I have cut apart and they need cutting into squares , strips etc. I have started making kits up for the quilts I want to make from my stash. It is more satisfying than going to the shop to buy more fabric.
