Well, it took me awhile to dig up enough baby and souvenir spoons at junk stores and yard sales, but I finally did it, just in time for her birthday this year!
It's a quick project once you have the materials. The mirror is a plastic-backed utility mirror I found at Bring, and I admit that I just hot-glued the sixteen little spoons directly to the back. Those that had dangly bits or handles that were too long or two wide were cut with tin snips first. Oh! And I alternated fronts and backs for some added interest.
I had a partial sheet of adhesive felt furniture pad that makes a good backing. It's thick, so the spoons won't be sitting directly on the wall, and soft so nothing scrapes. The hanger is made from a plastic coated paper clip sunk into the felt with the ends bent back on the other side. And then, for security, more hot glue holds everything in place.
I don't usually use hot glue so liberally in projects, but there was no place on this mirror to rivet or wire the spoons in place. In situations like this (small, light projects without an extended base) it's a good choice that'll last a nice, long time.
Happy birthday, Mom! Love you a bunch.
