Unless you like to make scrappy quilts, I do not recommend just buying random pieces of fabric just because they are on sale. I made this mistake when I started, thinking I needed to have a stash. Well I still have most of that fabric!! I have learned now to buy for a quilt pattern I have selected, and you will built a stash from those leftovers. The other random pieces just never seem to fit into a project. I keep thinking I will figure a way to use them, but after 2 years it still hasn't happened.
