I just published a new tutorial: create amazing cosplay glowing crystal gems! From the guide:
Crystal Gems will always save the day!
Create a stunning paper craft crystal from laminated cellophane wrap. Add NeoPixels and watch it sparkle!
We’ve included two different build sizes in this tutorial — one crystal large enough to house a Circuit Playground Express, and one with a single NeoPixel illuminating the crystal. This project can be run from a battery for cosplay applications (the crystal on Gandalf’s staff perhaps?) or plugged in to the wall via USB for a more permanent installation.
We’ve also included a Steven Universe Warp-Pad 3D printable base, so your Crystal Gems can be displayed in style. The possibilities are endless!
I absolutely love these gems. They’re easy to make with a few easily found tools. The main ingredient is cellophane gift wrap that’s been run through a laminating machine, which creates a perfect material for paper crafting — stiff enough to hold up but easy to cut with scissors or a utility knife. You can also get fancy and use a vinyl cutting machine to create perfect gems in multiple sizes. 3d print a base, or use the gem in a hanging lamp, or place it on top of your staff for a Gandalf-style cosplay.

I’d love to see the costume you accessorize with yours!
