Start with a plain egg. Press a small rubber stamp into an embossing pad (for white designs) or an ink pad (for colored designs), then onto the egg. For continuous patterns roll the stamp along the curve of the egg. If using an embossing pad, the design is difficult to see, so start with just a few designs.
Use a spoon to sprinkle clear embossing powder over the stamped design, then carefully blow away the excess.
Place the egg on a pin-board. Hold a heat embossing tool over the design to melt the embossing powder until it's shiny and solid. Repeat steps 1 to 3 to add additional designs.
Submerge the egg in a strong dye bath for 30 seconds at most (a longer time may loosen the design). Blot the egg dry with a paper towel, and set it on the pin-board to dry.
