I help with making baby quilts for my church to give out to charitable organizations. Fabric is donated, so we aren't always able to plan any particular pattern. Fabric is cut into 6" or 8" squares, and put into piles. I sort through the squares and separate according to color and intensity, and lay out each one on large poster boards so each color or pattern overlaps the other, leaving an inch to be able to overview the whole layout. Very easy to pick out squares that way. Poster boards can be carefully layed on top of each other and slid under a dresser, or other piece of furniture to store if needed.
