Threads Magazine has a "special edition" out right now, called Quilting from Scraps or something like that. It is great in sugggesting how you might store your "scraps/pieces" what qualifies for saving...e.g. bitty scraps could be saved for a bit...and then possibly toss after a set time. Also, how to store for light colors versus darks, and those "others" in between values. I can see how this might greatly simplify working from scraps. Plus the magazine is full of great scrap ideas for quilts without resorting to "scrappy" patterns.
