I have tried "emboss resist" before (from 2010 here), but then I have difficulty creating a card with it. This little 4x4 card actually took me quite a few hours, until I realized I should keep it simple.
Emboss resist technique:
Choose a patterned paper and a (mostly solid) stamp. I find this works best with small print patterned paper or a tone-on-tone print.
Ink with Versamark and heat emboss with clear embossing powder.
Ink with a Tim Holtz distress ink. Use a tissue to wipe of excess ink. (You could also sponge color on with any die-based ink or even use a Promarker/Copic marker).
OPTIONAL: I took a sheet of text-weight paper from my printer and put on top of the image. I used my iron (medium heat) very quickly. This removes some of the embossing and makes it less shiny. I moved my paper and briefly ironed again. There is still some sheen, but you could move the paper again and iron to remove it all, if you wish.
(paper: My Mind's Eye Miss Caroline
"Fiddlesticks"; ink: Tim Holtz "worn lipstick"; Magenta stamp)
At first I attempted to find coordinating card stock and coordinating Miss Caroline papers to layer and create my usual A2-size card (4 1/4" x 5 1/2"). Here was the problem: the stamped image (flowers) was lost and even I couldn't discern the image at all...it just looked like a swirl of colors, except when I layered it on white card stock.
I then tried to find a coordinating card stock, but I could not find the right tone. I grabbed a scrap of the Miss Caroline paper, cut my larger square layer, and inked a 1/8" border with the "worn lipstick" distress ink. Success at last! I added a rub-on sentiment from American Crafts. Done.
