Sounds like everyone is doing a good job on shopping the stash first. I'm rather proud of myself as I'm making a baby quilt in blue and was struggling with finding some fabric from stash. Nothing seemed babyish enough. Was determined not to buy any fabric for this (does anyone else feel like that sometimes?). Have plenty of fabric something should work.
I had a piece I kept coming back to but had some purple in with the blue. It's a batik. Then I thought I could just not use the parts that were a little too purple. The piece should be big enough to do this as it's going to be a 40 x 40 quilt. And this seems to be working out fine.
