Daisydawg: I've become a member of this site because I saw this thread when I was doing a web search.
I'm a user of "A Quilters Lumberyard" A Scrap Management System. The patterns and name are protected by the US copyright law. I don't receive any monetary gain from the Lumberyard system, I simply use it.
So now that said, here is my description of it. When I finish a project any fabric left is folded to fit on my shelves, except for pieces smaller than 1/8 yard or a fat quarter. Those I cut into lumberyard pieces. Most of the scraps are cut into 2 1/2 x 4 1/2 or 2x4's (with the 1/2 seam allowance) then 2 x 2's, 2 x 8's, 4 x 4's, and so on. Always add the 1/2 seam allowance to a lumber size. The pattern I use most is called Crazy Eight's, which is just 2 x 4's placed so that there are no matching seams to make an 8 1/2" block. It's a great way to make a scrappy quilt very quickly. As with all quilting very accurate cutting and sewing of 1/4" seams are important.
If you are interested patterns are available in Bend, Or at B J'S Quilt Basket 20225 Badger Rd, Bend, Or 97702 phone 541 383 4310. I recommend that you buy their pattern package that includes their first pattern, Crazy Eights.
