New Ribbon Storage

Have you seen this (scroll down to her ribbon storage post)? Well, it's about the most GENIOUS idea I have seen to sort ribbon. I am still wondering why I never thought of it! So i'm giving it a shot, but instead of using mat board, I have illustration board. And rather than illustration board for the dividers, i'm buying foam board.....it's a little thicker and I can comfortably put a few pieces of red line tape on the bottom to give it more support. My hands hurt today from cutting so much illustration board, but it's going to be SOOO worth it when I can get all of my bulky rolls of ribbon into a much smaller container. Mind you, I have about 350 rolls of ribbon, not including anything bagged up, or on clothespins.
