Here's what you can do with the ones you put in the "what was I thinking" pile. Make some small quilts for www.quiltsforkids.org
They give small quilts to kids in the hospital. They have to be small enough not to tangle wheelchairs, etc. And if you have really large pieces that you do not like, I am sure they would appreciate the donation.
I think purging a little of what is overwhelming you will make you feel good, and bring good things back to you as well!
