So, start with a leftover 1/2" mdf cut.

Whip out my crappy finish-woodworking skills and cut some 45s in a 1 3/8" x 1/2" piece of trim molding and add in $9.97 worth of cork shelf paper (self adhesive....the backing makes it sticky and tear resistant):

Cut the cork using the molding as a guide and a sharp razor. Then, dry fit the molding:

Another unfinished project on the bench. I'll be staining the molding with some sort of red stain, then making a spay paint template of something on the cork.

Hope to have this finished by next weekend.
