Homemade Cork Board
Corks, Corks, Corks by Angi
I saw a picture of a corkboard made out of different sizes of corks. I'm not sure how they made it, but I'm assuming they took an 8x10 frame and glued the corks to the cardboard backing of the frame. After the corks were dry, assemble the frame as usual, minus the glass and you are ready to go. I'm sure you could make various sizes and styles of cork boards.
