Take 4 black pipe cleaners and cut them in half. This will give you 8 short pipe cleaners.
Using your hot glue carefully glue 4 pipe cleaners to each side of your glasses. Be careful around the hinges, you don’t want to glue them open or shut.
Trim the ends of each pipe cleaner to taper the ends.
Bend each pipe cleaner in a sort of zig zag shape, spreading them out to look like spider legs.
Take your glow paint and make scalloped pattern around the lens of your glasses.
