I divide my 2.5s by color and put into zip lock bags. I have about 10 color bags then one of white/off white and another of blacks. I just dump all my bags in to a large 35 bag. Easy to dip in and grab a whole bag of pink or aqua or red. Along with trying to use fabric from my stash, I am trying to use the organizing tools I have at hand. (More money for other quilting needs.)
