Ok I think it may have been my fabric you saw. At least part of it LOL! I seperate general fabric by color. I also seperate by type ie Orientals, 30's, Civil War, Moda Marbels. and sometimes I try to keep lines together if I am going to design a pattern with that fabric. So that is how I determine where it goes. I also fold the fabric over a 6 by 24 inch rulerr just like it comes off the bolt. I slid it off and fold in half. I love seeing all the fabric neatly organized and as I said before I can pull fabric easier for projects.
