I love making scrappy quilts, so I'll probably keep saving them even though I also have more fabric in my stash than I'll use up in my lifetime. It seems I use up my scraps every year or two. I made several scrappy quilts this summer and got most of my scrap bins emptied (they are filling already though). Then I started on my jelly rolls - it never seems like it's all that much, but I had about 20 of them and only used up about 6 making 4 quilts.
One thing I've decided to start doing is using regular yardage for backings on smaller quilts (less than 80"). It will mean using two different fabrics on the back, but will get some of my less liked stuff used up. Especially some of the prints with really large designs. I won't use what I have a lot of, as I'm saving them for the times I'm making a quilt with a lot of background fabric.
