Found this idea and had fun playing with it yesterday. Uses the round tags with aluminum edges. I only had the small ones, which is pretty challenging, but a good use for tiny images from magazines, calendars, even tiny stamps although I haven't done any stamping for this.
I tried making some larger ones myself, using foil tape around the edges, but I wasn't really happy with the results. Here are the ones I've done:
I thought I might coat with Liquid Laminate and add some tiny rhinestones IF I actually use them! LOL!
The project I found that inspired me has a neat way to present them as gifts --tokens of Love, Thanks, Friendship, etc.
