Oh -- this would be hard. I would have to track the time I spent doodling or searching books to find the ideal pattern for my fabric, then all the time I spend pulling fabrics out of my stash because I keep thinking of a different color combination that I think would be fun, then calling DD to come to help me choose what to use, then changing my mind about the pattern. By the time I finish the quilt, I probably have more time in design than in the quilt itself.
