On NGS group we're doing a study of Tim Holtz's book "A Compendium of Curiosities", this week we're looking at the section "Water Stamping".
Ink card stock/tag/paper with Distress Ink, Tim recommends using darker, bolder colors for this technique. Using a blending tool to blend some of the colors if you desire.
Apply embossing ink to a stamp to help the water stick to the stamp, then mist the stamp with water with a fine mister.
Press stamp onto the inked card and quickly lift the stamp off the card, continue to stamp as much as you want, re misting the stamp as needed.
Dry the card with a heat tool.
Here's my finished background:
Here's another one I did, with lighter application of ink, and less water sprayed on the stamp.
