Most of my stash is on a concrete floor, so I do not have to worry about it! I "only" have 22 large totes and two cabinets full....The cabinets have the poly knits I use for charity quilts. I am positive that they are much better for those who have limited resources for care and washing---and they last forever. I pick up blankets are thrift stores and yard sales instead of batting, so they can be tied for a quick finish.
