I've been working on storage for my MS punches. I have 9 PAP sets and 17 other MS punches. I had all of them in one of the larger Waverly boxes. I had planned to move them because it had outgrown it and I couldn't get the lid down. I moved them to one of the bottom drawers of my new bookcases. Thing is, when they are down in the drawer I knew I would be rummaging to find what I needed because the most space efficient way to store them is up on their end with the handles up and then you can't see the nice graphic of the punch they have on the front. Not to mention keeping the PAP sets together.
My first idea was to get my small punches and make colored coded flowers or what ever to keep the PAP together, but I realized that will not let me see what design you are looking at. So I had an epiphany that if I punch the design out (corner for the PAP) that I can glue them on the back and be able to find the design I looking for. If I had done this from the time I started collecting punches and matched the color of the tag on back and make my example cut for my notebook that I thumb through the same color. It would be even easier. Still this is pretty great.
