I have been smitten for a while with little vintage slider boxes that contain labels and other office supplies. The best ones are the ones that look like little books. I check eBay sometimes to see what's out there. Bidding can go really high, really fast on the good stuff. Some people even sell the boxes empty, but I like them with contents.
I decided to cover some matchboxes and see how that would look mixed in with my vintage boxes. I gathered some papers for covers, but by the time I got ready to make covers, I didn't use any of those papers and used my good old stash of security envelopes instead. I put a white sticker on what would be the foredge of the fake book. One of my vintage boxes even has fake pages and dividers.
It turned out pretty good, but not the same as the vintage ones. Plus the matchbox is smaller. But at least I got it out of my system!
