I have some of mine hanging in shadow boxes with the hinged fronts that I bought at Michaels craft store (get them when they're 40 or 50 percent off- then they're about 17 dollars). I covered foam board with black fabric as a base to hold the pins. Now I can stick the pins right in (no pin backs) and rearrange them whenever. That's it. Easy and they look great. I label my empty cards and packages and put them away in case I want to trade/ sell any of my pins in the future so I know who belongs in/on what (too many scrappers and counterfeits out there not not keep them when you can).
