When I was browsing through Michaels a couple of weeks ago I picked up one of their 12"x12" buralp canvases. I really liked the deep gallery wrap of the canvas and it's clean lines. I debated whether to gesso it or use it for a collage, until I reallized it would be the perfect size for the space next to my computer - where I really needed a small bulletin board to help me keep organized.
I also had a bunch of scrap pieces of cork lying around, which was a great way to use what I had.
This .5" thick cork came in a pack of four (or six?) pieces. I'd used about half the pack on the inside of a kitchen cabinet door and the rest has been sitting around ever since.
First, I fit my cork pieces onto the back of the canvas. The burlap was loose enough that I could slide the cork under each side of the frame. With this thin cork you can easily bend it under each edge without it breaking.
I was able to use about an 11" piece. I was thrilled that you can't tell where the cork stops on the front of the canvas; it's just a nice, smooth surface.
Here's what the bottom layer looks like. Mine is made up of pieces because that's what I had. If you were to make this you'd need to cut at least two pieces of cork so that you could slide them up under the frame at the top and bottom.
Once I'd fit my pieces into place like a puzzle, the seams were taped with duct tape so they wouldn't move around.
I had just one full-sized sheet of cork to use and saved it to use as a second layer. I cut it to fit just the opening in the back of the canvas. I just placed in the back of the frame, no gluing or taping necessary.
You can cut cork pretty easily with a ruler and a craft knife. Or a good pair of scissors will work too, like these Tonic ones from Tim Holtz.
As a final backing I cut a scrap piece of thick chipboard and glued it to the cork using a liberal amount of the Best Glue Ever. For stability I used duct taped to secure everything to the frame. The only thing left was to add a hanger.
Voila! My new memo board, ready to hang.
