Your quilt turned out great. I'm working on a Scrappy Trips right now and am having a hard time breaking out of the dark/light/dark/light fabric placement. I don't think my quilt will be nearly as gorgeous as yours. But, as you say, a learning experience - and a great way to get a lot of fabric out of my stash.
Be sure to show us the finished quilt. I'll be anxious to see if it ends up with borders or no borders.
