I got a large piece of dark fabric that wasn't showing pin marks and sewed a pretty wide opening at the top seam for a wooden dowel. I have like 300 pins and that way I can display them all together. However, it does get really heavy - I had to put up extra reinforcing holding hooks (I bought those 3M ones that you can stick and remove anywhere). I have a pic somewhere, I'll come back and add it. My sister who has not nearly so many had her SIL paint a background of pathway, twilight sky and fireworks, and she is making a castle shape out of the pins - that looks great too. That has a shadowbox style frame.
