Since sealing the paper mache eggs with Mod Podge worked, I figure it’d work on other paper mache items, like this star box:
Then I thought…Hmmmm…glass is non-porous and glossy…why not try it on a small votive. And wow, it turned out great!!
I cleaned the glass off first with rubbing alcohol. Then I added a drop or two of alcohol ink at a time and then sprooshed it with the canned air. Sooooo cool!
Edited to add: I read on the alcohol ink labels something about it giving off toxic fumes when heated, so beware if you’re using this craft near an open flame.
