UPDATE 1/26/2021 – Here is my up-to-date Wakelet collection of Valentine’s Day resources.
According to the Origami Resource Center, Puzzle Purses have been around for centuries in several different cultures. In Victorian times, they became a Valentine tradition. You can find specific directions, along with diagrams, for folding your own puzzle purse, here. As an additional challenge, your students can also create the poetry that goes inside.
