Marcia, there are lots of scrap quilt patterns that would look great in your fabric collection. Maybe even just a baby quilt if you don't have enough for a big one.
I know just what you mean... I am working on a Farmer's Wife Pony Club quilt and I have collected so many great fabrics for it... I probably have enough to make 10 PC quilts! But once you have a collection together you can do other quilts with them. Fabric selection is done!
