I'm trying to create a cork bulletin board for my cube, but having
trouble with ideas for the solid backing for the cork. My first attempt
was to have two layers of 3/16" cork over hardboard. The thumbtacks
don't stick into the hardboard. I went around the BigBox today and
couldn't find any materials that would accept a thumbtack.

Anyone got ideas? I'm not married to cork as a material.

Aha! Thanks!
