I believe that the easiest and fastest way to do Metal Embossing is by using Stencils. They are great for fast and easy- to -do projects. Stencils can be used with any metal but Colored aluminum seems to be the perfect match.
Here I used:
Dreamweaver’s heart stencil LL567 and
Mercart’s Bronze and Red aluminum. Dots around the hearts were done with the “Star Wheel”
Instead of embossing the design, I chose to “deboss” it. The backround was done with Fiskars textured plates. I sanded the aluminum to remove the color.In particular places you can also use the Brass Brush or the Fiber Glass tool to remove the color.
