No way. I expect my hobbies to give me pleasure, otherwise what's the point? It's a hobby not a hazing.
If I love the fabric I salvage as much as possible and put it back in the stash. If it's the fabric that I end up disliking, sometimes I toss it but a few times I ended up painting it using acrylic paint mixed with fabric medium and that was fun. I made a couple of small art quilts with that fabric.
