Fabric has no expiration date. I've had a yard and a half of fabric I had no clue if I would ever use -- anytime I tried to put it in a project it just didn't work -- until yesterday! Now it will be used in a denim cathedral window quilt. The few inches I have left over will be cut into strips for my string quilt box. When you have fabric you don't know if you will use, do what makes you happy. If you feel less pressure on yourself by giving it away then do it. If you can put it in your stash for another day then that is great too.
