We sell these decorative Rte 66 license plates, and I've had my eye on one for awhile. I finally figured out what I wanted to do with it. I cut it into 3 pieces, one large one for the back and two smaller ones for the French window front. I filed the raw metal edges smooth then covered them with strips of black leather. I drilled holes at both sides, folded beige paper into 6 signatures for each side and bound each side with black hemp cord in a single-needle coptic stitch.
It still didn't look finished, so I added the chain and an "S" hook clasp to hold it shut. I like it.
