Step 1: Preparing your heat shrink design
Stretch the image height until it is 4 times taller than it should be (now you see why your stacked 4 high). Delete the everything but the stretched image and print it.
Take your smooth piece of party cup and tape it to the computer paper. Make sure it’s taped directly over your reference image. Place the paper back through the printer. Now you should have a stretched printed image on the piece of cup.
Step 2: Heat Shrink
While doing this the plastic started to dance around my work surface. I just opened a pair of scissors and used them as a backstop to keep it in place.
Be mindful of anything that may melt or burn including yourself. Also use a well ventilated area. No visible fumes come about while doing this though it does release an odor. Good ventilation is never a bad idea.
Step 3: Seashell Pendant
For the jump ring fashion a loop out of the same plastic and super glue it to the back of the pendant. Cotton cord makes for a good necklace.
