LED Butterfly Pop Up Card
Step 6: Prepare Pop Up
Use a hobby knife to cut along the lines of the pop up template.
Tape or glue pieces of vellum or a semi-transparent paper to the back of the wings to help diffuse the light from the LEDs.
Fold the page in half and crease.
Then flip the pop up over to the front side and carefully pull the wings toward you to make them pop out from the page.
