I belong an ATC group and we are doing a Black and White set. I just bought a new Magenta Stamp so I decided to use it for this swap.
My first thought was to use vellum and stamped and dry embossed it but I was not happy with the result. I decided instead to stamp a Hero Arts small background on the black cardstock in white. My first attempt was with white satin embossing powder, which looks more silver than white on the black cardstock, so that was put aside.
I then stamped and embossed the background with white opaque embossing powder, which looked much better. I stamped and embossd the Magenta image in black on white cardstock and cut it out with a small halo. I attached it to the background with double-sided foam tape.
