I'll try to find the rest of the cork sheeting that I used Stig. The cork is on a sheet with a self adhesive back. I simply cut the cork sheet to the length and width needed, and affixed the glued part to the side of the "standard". Have you any art supply stores where you are?
If you cannot find what you need send me a PM with your address. I'll try to get to the store over the next few days and get a sheet off to you.
