I had never heard of this technique, but you emboss the first layer in clear powder (twice if you prefer). Then you take a solid stamp and use a colored embossing powder and stamp it over the clear. When you heat up the colored powder, it melds into the clear layer.
Here's a close up shot:
For the details of the card, I used a Memory Box patterned paper for the clear embossed background and an Inkadinkado butterfly for the black embossed layer. I laid that on a Tim Holtz embossed background and added a Hero Arts sentiment
I'll admit, I had to try this technique twice. The first stamp I chose didn't work out too well. I suggest definitely using a solid stamp for your colored embossing powder layer - if you chose to try this!
Have a wonderful Monday!!!
