I came across this looking at pop up cards to make . I thought , what a clever way to create a small self closing gift box. Credit given to Jennifer Maker ( https://jennifermake...impossible-box/) and to Julie at (https://thepaperpixie.com/) for her video tutorial.
As you make one, you will notice it looks like half a square Christmas Cracker, but the twist is how the end folds over. Enjoy making one yourself - super easy.
