Play Ball and Fight FascistsSandblasting was fun and easier than I'd anticipated. Would love to do this again with different types of glass.
Started with this (thank you Sketchbook mirror function so I only had to draw half a butterfly.)
Then lots and lots of careful cutting of contact paper, and getting it onto the glass.
Video to show the iridescence!
On this one, the hardest part was a) getting the contact paper cut out, and b) getting the damn *backing* off the contact paper.
