Next you need to attach the ribbon. We have found that the ribbon holds messages best if you position them at a 45 degree angle to the bulletin board. They should be anywhere between 4" and 6" (10-15cm) apart. We made ours parallel to eachother, but of course you can get creative if you like. Measure out the placement of the ribbons and make small pencil marks wherever you want to place them. Wrap them around the edges of the board and tap in a tack at each end (on the underside of the plywood) to hold them in place. You can also use a staple gun for this step. Note that our fabric had a checkerboard pattern and we used this pattern as a guideline for our ribbons; it gives a very interesting effect.

Once you are done, you can tap a tack into each intersection of the ribbon. The final step is to attach a hanging device to the back: you can treat it as you would a heavy framed painting. You can use a hook or picture wire; whatever you do make sure that the board will hang securely.
