These sweet stamps let teachers say "great job" with ease, and they come together fast from cork and adhesive-backed craft foam. Packaged with an ink pad and a gift card to a craft store, the set is a great way to say thanks for a stellar year.
Use the nail file to sand the wide end of the cork flat, if necessary.
Draw or trace a letter or shape on the back of the craft foam. Cut it out and press it onto the cork. Repeat for the other three corks.
