I went to a quilt fabric sale while back put on by group of quilters in Fountain Valley, CA it was outdoors and we had rain believe it or not so the ladies decided to sell fabric by the piece instead of cutting and that when I bought about 2 yds of black but didn't wash it until this week with other dark prints. It wasn't until I took them out of the dryer that I saw the black all shredded to my horror and it left some thing on the other fabrics I had included in the wash. I tried removing the black what ever with masking tape the best I could and it took for ever. I have never experienced fabric shredding like that before. Do you think it was old? It felt sturdy I just never even gave it a thought. Definitely very week after going thru the machine.
