Step 2. Once the plaster is dry, insert the bottom of your tree branch into the foam board as pictured. In a separate container, mix more plaster and pour it into the container with your tree branch, covering the foam board until it is no longer visible (as shown) Let the plaster dry. During this processes you can also insert any small containers you might be incorporating in your jewelry holder. I inserted my small saucer plate in this step). Step 3. If you just want to paint your jewelry holder and be done, paint the branch and dry plaster with the color(s) of your choice. I used joint compound to add broken pieces of ceramic and flat rocks to the plaster base, as pictured. I also made sure to give the branch a thick coat of gesso with a brush that would get in between crevices and holes in the branch. Then I let that dry before I painted the branch silver. Whatever your preference, let the entire project dry and smooth out any rough edges on the plaster with a piece of cloth and water.
