Mounting a large number of items

[beginningframer]

This is definitely a beginner question but my research has come up with a lot of conflicting information, none of it really useful. I have over a hundred media credentials along with some other mementos that I’d like to frame and hang on a fairly large wall. Since I’d like to put the layout together myself, this is going to be a DIY project.

What I’m looking for is some guidance on the best way to mount these (most plastic, some cardboard, some paper) before framing. What is the best background to purchase, and how should I mount them to the felt so that they stay in place when hung on the wall but are not completely ruined if I ever want to remove them?

Any advice here is greatly appreciated. Thanks in advance for your time!

Welcome to the forum, this is a UK Framers forum, you will get better advice on the US Forum
