And guess, what?? It works!
I used my embossing buddy liberally all over the tin first, and then stamped flowers from Fifth Avenue Floral in Versamark. The tin is quite a slippery surface, so be careful not to smudge the stamp. Then sprinkle with silver embossing powder. You may need to use a small brush to get rid of any stray bits of powder. Then heat with your heat tool. The tin gets quite hot, so don't burn yourself and allow the powder to set for a bit longer than normal. Because the tin stays hot, the powder will stay molten longer than normal. Actually, I added the DSP (from Bella Rose) to mine because there is smudged embossing under there! (sshhhhh!). I stuck it on with tombow glue, and the ribbon and tag just slide on and off so the tin can be opened.
The tin I used is one that you get with the Flower Fusion Felt flowers. I've been going through a ton of the flowers, making cards like this:
What a difference, huh? It makes me want to go back and GIMP all my photos (but that would take waaay too long!)
