The heart-shaped picture frame shown in the left panel was designed by Mike Van Horne. It’s a nice and easy origami model folded from the windmill base.
For the variation shown on the right, I added a few more folds that made for a firmer lock, removed the small white “slits” and produced the solid red color on the sides.
Here is a video to fold the windmill base,
Have a happy Valentine’s Day!
