Just a word of warning....if the fabrics were stored in wooden containers, the stains may be oils from the wood and will be very difficult to remove....I tried to remove stains from a older quilt top stored in a cedar chest and the risk to the fabric was too great to continue....I am in process now of finishing the quilt (my mother completed the top) and will love it (stains and all) when finished....some things just aren't worth messing with!
