Then I chose my colors. I used Americana Sand, Sable Brown, and Mississippi Mud. While not pictured here, I also used Bleached Sand.
I started with a Styrofoam 15/16 in x 15 7/8 inch Disc I found at Michael’s.
Using a craft knife I cut around the edges of the Styrofoam disc to create a sand dollar shape. Next I used a craft knife to carve the design of the sand dollar into the Styrofoam disc.
I made the carved indents a bit deeper and wider using the handle end of a paintbrush.
Now you apply 3 coats of MagiKote to the top, sides and inside the indents of the Styrofoam disc, allowing 2-3 hours dry time between each coat.
Apply 1-2 coats to the back as well.
Sand the entire surface to remove any rough edges.
Paint inside of each indentation with Sable Brown.
Paint the entire top and side surfaces with Sand.
Make a white wash by mixing 1 part Bleached Sand with 2 parts water. Use paintbrush to apply white wash over the entire surface. Gently wipe off excess with a dry cloth. Continue applying and wiping until you reach the desired affect.
Use paintbrush and Mississippi Mud to add small lines around all of the star’s arms.
