I just filled a big bag with fabric that I know I will never use. There is nothing wrong with it but I bought it when I was first starting out and my tastes have changed a lot. I was making lots of charity quilts for kids and in a more traditional way. I still make them but they are modern now and more solids and modern fabrics so no point in having them take up shelf space. The fabric will go to a group that makes lots of quilts for hospitals, hospice, etc. And yesterday, I just gave a friend a large self healing cutting mat that I no longer need. By all means, recycle!!
