Gather your supplies.
Melt the soap according to the package directions. Usually you will have the option to either heat the bars on the stove or in the microwave.
Add the soap dye. For the brown color, I used a combination of (mostly) yellow, blue and red.
Once you have achieved your color, pour the soap into the soap mold. I used an oval shaped mold that I purchased at the store, however, you can use almost anything as a mold for soap.
Once your soap is cooled off, pop it out of the mold with a little pressure. Using a pencil, gently draw the symbol on the bar.
Using your carving tools, carve the outline that you've drawn on your bar. I used tools for clay, but you could also use something from around the house, like a flat head screw driver.
Make sure your design is carved deep enough to fill it with the green soap.
Make another batch of soap but color it green using yellow and blue dye. Very carefully pour the heated soap into the carved design on the bar. You can also use a small spoon or wooden stick to drop in the soap.
If you didn't get a perfect pour, you can use your tools to even out the design.
You're done! You can polish the bar with a paper towel and a little bit of water. Check out more handy crafts at World of WarCrafts!
