Using up scraps

I only started quilting last spring, but I am already being swamped with scraps. I've already use quite a lot on some little bags but it doesn't seem to make a dent in the pile.

I have been inspire by the wonderful quilts on http://heartstringsquiltproject.com/ and have started a string quilt. Until you get a number of blocks completed and lay them out it is hard to tell if they are going to look okay but I've now finished 20 6 inch blocks and when put out on the floor I think they blend together really way, even though there are really random fabric in there.
