When lit, they glow. It's really pretty.
I intended to make a photo tutorial, but I neglected to take pictures as I went along. And I didn't blog them immediately. My memory isn't perfect, but this is basically what I did:
Clean mason jar(s)
Glue gun and hot glue
1. Thin the paint slightly by adding a drop of water. Paint the inside of the jar, let dry completely. Repeat until desired opacity/transparency is achieved.
2. Cut each cinnamon stick in half lengthwise. I found the score-and-snap method easiest.
3. Glue cinnamon sticks to the outside of the jar.
These pics are from the first one that I made. I didn't quite have enough cinnamon sticks, so I cut a few into quarters lengthwise.
