I like the jelly roll sets idea, but like Patrice, I find the price too hard to swallow. However, I would like to be the one selling them!
I saved all the scraps from my daughter's black and white quilt and cut them to the same width. They are not the same length, but I have been rolling them and at some point when I don't have 30 other quilts in my brain, I will just start sewing as they come off the roll and see what I get. My first stab at free form quilting. If it works out well, I plan to do this with all my scrap strips.
It does tend to remind me of building a rubber band ball though. LOL
