I do know exactly how you feel and it was never more apparent than when we had to downsize from a 3-bedroom house with full basement to a 2 bedroom apartment. With 2 sewing areas, one in the basement and another upstairs for quilting in the winter, I lost track of exactly how much I had, especially having inherited my sister's stash when she passed away. My dear friend inherited a lot of it but she also passed on fabrics to be used for charity quilts, so the fabric was put to good use. Now, unless I need a specific fabric to complete a project, I am doing pretty well shopping only in my stash. It was sort of "cold turkey" therapy, but it seems to be working.
