Use your fingers to apply a thin layer of petroleum jelly to the sides and bottom of your box. Remove any excess using a paper towel. Do the same with the bottle, then place the bottle in the box where you want the hole to be.

For each cheese board you'll need a cardboard or plastic "form". Lightly coat the bottom and sides with petroleum jelly and wipe off any excess with a paper towel. Coat the sides and bottom of your bottle as well, and place it in the mold where you want your hole to be.

Pour 1 cup of the plaster of paris into the quart container and add your pigment. The amount of pigment you add will depend on the intensity of color that you want. If you buy the pigment I used, for reference I added the entire packet for each board. In the case of the pink it was way too intense, but the other colors were more mellow and more to my liking. So add less and increase the amount if needed.

Use a popsicle stick to mix the plaster of paris and pigment together, then add about 1/2 cup of water and stir quickly and thoroughly. The consistency should be as thick as paint, smooth and "pourable". Immediately pour into your mold, using the stick to guide the mixture around the bottle. Gently shake and tap the mold to level the mixture and let set overnight.

Used the exacto knife or scissors to cut down the sides of the mold and release the board. Wipe off any petroleum jelly.

Sand down any rough edges if desired, then apply a layer of matte medium. Let dry, then add your suede lace.
