Let's say I'm working on 2.5 squares. I put each color in a zip lock bag by themselves, then all 2.5 zip lock bags in a bin . Same thing with other sizes - I cut 1.5, 2.5 and 5.0 by WOF strips. Each color in a bag, all the bags of the same size in a bin together. Fat quarters and sorted into bins by color. I love the bonnie hunter system.
