Well, what sizes of scraps are we talking about? I tried all sorts of methods for scrap control and finally decided I simply didn't want to deal with little bits and pieces. My designated storage has 6.5" strips, anything smaller than a 6.5" square and I toss (or put in my crumb quilter box). A consistent size or width really helps storage. Some people like 2.5" strips as the smallest they save. I figure I can always cut down a 6.5" piece, but I can't really cut up a 2.5" piece.
I created projects specifically for scraps. Made lots of string "fabric" to use in that sort of design. Log cabins are another good way of cutting down pieces.
And then there is simply looking at the fabric and do a "love it" or "not so much" and keeping only what you love and/or think you will actually use.
Best of luck!
