Somebody will be very happy to have the fabrics and supplies that you no longer want. I go through my stuff often. I like to shop my stash as much as possible when I make my quilts. Whenever I empty a project bin, I am able to reuse it for one of the projects in my "stack" of projects. Eventually everything is going to fit in my closet. Everything used to fit nicely until I inherited my MIL's stash.
