My sister has taken up buying patterns for me for Christmas - one I am anxious to try but the others are cute/attractive but nothing I care to make, so I hang them on my wall and admire them. Fabric that has been given to me I go through and keep what fits with my stash, the rest goes to the thrift store.
People giving you fabric, you can either make a quick throw and give it back to them. Maybe they will get the point. Or just give it away. There are a lot of people out there that need a warm blanket. My sister started making wrap arounds. (They are like a shawl with corner pockets for your hands and wrap around the shoulders to keep the person warm.) My mother was constantly cold and they worked so well for her while watching tv. And a bit more attractive than the commercial snugglies.
