I have gone back and forth on this issue, and I've decided I'm prewashing everything. I'm just not willing to risk a quilt's worth of hard work to bleeding fabric. I've tried all the methods to prevent fraying, including stitching the raw edges together first (what a hassle, and it still frayed). My conclusion is the good old-fashioned pinking shears are my best bet. And I can instantly tell if a fabric has been washed or not!
It's funny you posted this issue today. Yesterday it was poor Krystyna, who had cut a ton of strips, and watched in horror as they shrank before her eyes. If bad news comes in threes, somebody better watch out. :shock: :shock:
