Wooden puzzles are great toys in their own right, but magnetize them, and watch the attraction grow! Because wooden puzzle pieces are thick, they adhere best to magnetic walls if they have a complete magnetic backing.
Making wooden puzzles magnetic takes a bit more time. First, trace each puzzle piece, keeping them in order to make best use of the magnetic sheet. Cut out the shapes and peel and stick. Because tracings tend to be a hair larger than the actual pieces, you will need to trim each piece.
Holding the craft knife at an angle, slide the blade around the puzzle piece, removing the soft magnetic backing which overlaps the edge.
