To make your own set of wooden blocks, you will need: a package of 2" x 4" labels, a 2" x 36" x 1/4" piece of balsa wood cut into 4" pieces, a rubber stamp set, a pencil, sandpaper, and a fine black marker.
Stamp the words onto the labels...
Apply the label to one side of the block.
Draw a matching picture on another label, and apply that label to the other side.
This one is my personal favorite......
