Yesterday I went through that huge box of fabric. Luckily only the box was huge and it was not full. I kept a few pieces of bright cotton prints for myself, and set aside several large pieces to take to sewing group to give away.
The rest of the box was scrappy cut-up pieces that I put in a trash bag. Yes, I am throwing fabric in the trash. We used to have a few people in the sewing group that would take all fabric scraps and use them to stuff pillows for dogs for the animal shelters. They have stopped doing that for awhile, and I don't have space to store scraps until they start the project again.
The cardboard box is too large to use for anything I have, so it is flattened for recycling.
Today another short stack of magazines is ready to toss in the recycle bin.
