I don't make "bundles" per se, but after getting ready to make a project from a quilt magazine and not being able to find the pattern/fabrics, I started putting the magazine, with the project marked with a Post-It, and some or all fabrics needed to make it. As several of these projects require Wonder-Under, as I trace the pattern, I add that to the large zip-lock bag as well. My girl friend introduced me to the rather large zip-lock bags you can pick up in the grocery store, so I have a small tote with these projects in them. I seldom hesitate to pull a fabric from any of those bags if it's needed for something else. For future quilts, particularly baby quilts, I tend to iron the fabrics, then put them in a shorter tote, so they are ready when I am. Heaven forbid I get any more organized than that, because then I will forget completely what I had planned to do with the fabrics.
