Well, I was planning to make shopping bags (just fabric, not quilted) that fold up and go into a smaller, drawstring bag. The kind of thing you would just stash in your car for shopping emergencies.
However, I love the idea of those first-aid rollups that mollysmom suggested. I found this tutorial online; not sure if it's the same one she used but it looks nice and easy (and quick)!
