A bright and cheerful birthday card of origami pinwheels.
I cut the sentiment from matte black vinyl.
I cut the squares 2" to fold down to 1".
The fold is like a 4-petal flower base, with the corners tucked in.
Here the corners of the pinwheels are folded up out of the way while I glued the squares to the card front.
I used a dab of glue inside the pinwheels to flatten them.
The points are opened up again.
