I can't believe I haven't tried this out before - layered embossing....
For this, swap the organiser shared some step by step instructions for the technique and we could make whatever we wanted. I decided to play safe and work on an ATC for my first attempt, using very sturdy board as the foundation.
Stage one - cover the entire front with Versamark ink. Then using at least three colours of embossing powder cover bands of the surface in turn before heating to melt. I discovered that my stash of embossing powder is more limited than many other things - black, white, clear (no good for this) and metallics mainly - so I struggled to find enough variety for this experiment.
I used green, blue and bronze in the end for the first layer.
Step two - apply some more Versamark randomly with finger tip - smearing to avoid finger prints the instructions said, although for a future project I like the idea of deliberate finger prints. I applied silver embossing powder on this layer and heated again.
Step three - using a background stamp (the line stamp from a Paper Artsy Hot Picks plate in this case) apply more Versamark and emboss in white.
Finally stamp the main image in black.
I then added a final layer of clear embossing powder melted on top to even out the surface because some areas were a bit pitted, as if the chipboard had absorbed the Versamark and not grabbed enough powder even with all those layers.
The result is rather limited by the colours I had to hand but if ever there was an excuse to shop this is it. I need some pretty colours to play with further.
