I am chair of the guild's community quilt project. When I got all the fabrics I started sorting on the living room floor and furniture. (I don't have any pets - travel to much). Larger pieces were sorted by color. Smaller pieces also by color in zip bags but in a separate container for scrap quilts. I have them in clear totes (not to big they get to heavy) to be able to see what is in them.
This makes it easier for me to put kits together for the ladies to take home.
