Magnetic bulletin boards are handy, but the color options are limited. Make your own and you can match the powder blue of your kitchen. First, paint a prestretched artist's canvas. When it's dry, turn it over. Coat a piece of cut-to-fit sheet metal with spray adhesive, and attach it to the back of the canvas. Place a same-size piece of foam board on top of the metal. Then screw mirror clips (one on each side) into the frame and a sawtooth hanger on the back, toward the top. Glue ribbon around the edges for a finished look.
