Good ideas, to consider. Figure out what works for you. I'm in for organizing by color. When you do use those pieces, think of pulling out fabrics of similar intensities..like brights with brights; country shades with country shades...just be consistent and you will sew up a good looking quilt.
This is a simple quilt I made from scraps, but you can use with longer pieces, too. In this case I used homespun plaids.

Good luck with your sorting and your quilt making!
