One of our Valentine's Day activities was to create a picture frame out of puzzle pieces. Well, the only puzzles I had that were small enough to make into a frame were my Melissa and Doug puzzles. Those puzzles are too expensive to turn into a frame, so we changed the activity a little bit. We took the outside edge pieces and traced them on construction paper.
Using a glue stick, glue the picture on the cardboard. Then glue each puzzle piece on top. We wrote on the pieces and placed stickers on them.
Glue a magnet on the back so you can display your frame.
