I'm working with 1.5" squares right now, I finally picked out some by color and put them in paper bowls. Still totally scrappy but I'm not riffling through the box of cut squares, squishing and unraveling. It is working very well. When the bowls get about 1/2 used, I refill from the big box,
For a bit of control you could even do all green 4 patches, etc so it won't make you completely dizzy looking at the quilt
