Hsweany you pick your own fabric. Each of us will be making the same blocks but with our own color choices. You will need enough to make at least 12 blocks. But you can use a whole bunch of different fabrics or just a few. Also you can chose to do just a few of the blocks as they come up its all up to you. I know I am shaking about the challenges ahead but figure everyone can help me out if I get stuck (LUCKY YOU GUYS!) and Sulabug is starting us out and she is a great teacher so its going to be much fun. I am going to pull fabric from my stash and probably decide once I see what the first block will be. I am thinking browns and soft rose and ivorys a comfy quilt but heck I might make amish for the real challenge of it all.. now that is pushing all my buttons for sure. Or modern fabrics would take me out of the old sofa comfort. this is going to be fun!
