Ink a bold stamp with clear embossing ink (not perfect medium or watermark ink) and mist the stamp with water. Then stamp onto inked paper and lift off. Don't let the stamp sit on the paper. On this one, I think I misted with too much water.
I did the same thing again, but misted with less water, once on the bottom half of the paper (still fairly wet) and stamped again on the top half of the paper, using even less water. This will make great background.
