Fabric tends to multiply - based on impulse purchases, purchases for the "soon Quilt" and other reasons... I have been working on only stash based quilts for the past year.... guess what... IT DIDN'T MAKE A DENT!!!! I have now boxed quite a bit up that I am going to take over to the St. Vincent close to here. Owning a bunch of fabric that isn't going to become something - doesn't do it for me.
Enjoy your fabric, or sell it, or give it away if it is really making you miserable. Remember, this is our hobby and hobbies are supposed to fill our spare time with fun, creative and fulfilling activities.
