This card has such a soft subtle look that is very easy to achieve.
The background is more Glimmer Mists. Can you tell how much I love those Glimmer Mists?
You could use this technique on plain paper and get a similar effect.
Stamp your image with VersaMark and apply clear embossing powder. This causes your stamped image to be several shades darker than your paper. No matching embossing powders! I love it. Great results that are fast and easy.
The botanical stamp is by Fred B. Mullet. This company has some fantastic botanicals and fish fossil stamps. Very high quality rubber that stamps beautifully.
The second card uses the same technique with one difference. Some of the images have been embossed with fine line gold EP.
Note that the edges of these cards have been sponged with black dye ink.
This technique can also be used to create very interesting backgrounds.
