Quite some time again I posted this picture from a post showing how to use magnetic mats to create a border frame straight onto your card.....
As you can see they look insignificant used alone - but with a bit of layering, wire, beads and my Nestie squares....not too bad!
IF, you should NOT have a magnetic mat, you can still emboss dies in this way with your Bug.
The Sandwich is
A / tan mat / card / die cut side down / possibly shim(s) / 2 B plates
TIPS : try without shim first to test pressure
