To answer your questions, I keep the matches in a large glass container, atop the refrigerator. My mom had this glass container that looks like a barrel, complete with handle. I keep the matches in that all the time, but now that it is full, I will either have to look for a larger container or figure out a new way to display them.
I saw a display once, that consisted of a felt-lined frame with small dowels running across it horizontally. He folded the matchbooks around the dowels and they hung there in the frame. That works fine for folding matches, but some of mine are in boxes and I haven't figured out how that would work unless I use only the box tops.
Anyone have any ideas?
