Heat embossing is easy to do and requires only a few things to get started. While you can buy many different colors of embossing powder, try starting with white, black, and clear. If you have any watercolor paints or ink pads, you can color your own patterns after embossing with the clear powder. You will need a heat gun, embossing ink (some type of sticky ink- I happen to like Versamark watermark ink), embossing powder and a stamp to get started.
Blue opaque embossing powder (Wave Zing! embossing powder by American Crafts) on the same three papers: white and black cardstock and vellum. I love the look of the Zing! powders on most papers, but especially on black cardstock as it is super bright and truly is oqaque.
This is a clear embossing powder on the same three papers: white and black cardstock and vellum. It looks almost the same as the black powder on the black paper. I like the clear powder especially for using Distress inks to color over an image. I will often emboss an image in clear powder and then go over the paper with Distress inks to create my own backgrounds. The embossed image will resist the ink, and the original paper color will show through the embossed area.
...and as always, happy creating!
