This happens to all of us. When I first joined the board I was in a big rut. Looking at lots of quilts, but not sewing any. then I made a square for someone who was making a quilt for a cancer patient, and that got me going. Having a deadline to do something for someone else helped me , and now I can't stop sewing! :D :D Set a small goal, and then go from there!
sit down with your stash and handle it for awhile , maybe that will work also.
And , I am still making squares for others! this is a great motivation.
