to your plain ole' boring picture frame.
* picture frame (any size but make sure your dimes will fit).
* dimes (or pennies, nickels etc).
* epoxy resin (any brand is fine).
* Tarn-X or CLR stain/tarnish remover.
* mixing cup.
* stir sticks.
* glue (I used white glue but any glue will work. Just needs to hold the items till epoxy is poured).
Pour the cleaner in the bowl, put in your dimes and give them a swirl.
Now pour only the cleaner from the bowl, then give the dimes a rinse with water.
Dump them onto a towel and dry them.
Once dry, start to arrange a few of your dimes on the picture frame without glue. See what pattern will work for the size of frame you have. You may get away with the staggered pattern or maybe only the side-by-side even pattern (see pics). On the surface of the frame, the wider area you have to work with - the better options you will have. The smaller the surface area of the frame, the harder it is for placement of the dimes to work together. It may take a bit of time to figure out a configuration that will work.
Once you figure out the pattern that'll work for your frame, start gluing :~)
I just dipped my Q-tip into some white glue, put it on the back of the dime - then carefully placed it onto the frame. You should have a damp rag handy for when you unintentionally drop the dime onto your work :~(
