I follow the bonnie hunter method of scrap organization but nothing narrower than 2.5". I don't like to work with stuff that is too narrow. I also noticed that we recycle alot of paper at my job so I am going to grab some of the paper that is tossed out and cut it into 3.5" strips and just sew the very odd shape scraps onto them. Eventually I can use the crumb papers to make a quilt.
