First of all I will say, I have not read all the posts, so IF this was posted before, sorry. Do you happen to have a spare bed? Fold your fabrics so as not to cause a bump, and lay them under your quilt/spread. That way if you need a pc, just turn the bed down and there ya go - nice and clean, dry & light free. If you get your stash revived, then you can add to the layers. I guess if you have company very often, you need to have a plan as where to store the fabric til company is gone...;o)
Just a suggestion.
