A corkboard is handy for posting reminders, but it's often difficult to find a suitable spot for one on the wall. Instead, cut one to fit inside a door or a cabinet panel. Measure the dimensions of the space. With a straightedge and a box cutter, trim a piece of sheet cork (available in many hues at home-supply stores) to those dimensions. Affix cork to surface with nails.
