I went with the title “Urban Decay Earrings” because I thought it sounded so much better than A) “Yet Another Nail Varnish-Related Craft— honestly Emily, do you have nothing better to do with your life?”, or B) “Cardboard Earrings”.
So this was a total steal. I saw this—

“How to make earrings from cardboard” by Claire Coshan aka 3cardmonte
This one & several others can be found in this post on Hubpages, and they made it sound so easy I thought I would see if it was true.
Basically, you paint a bit of cardboard with one coat, let it dry, coat it again, then put it in the oven till it bubbles.
So I cut some circles out of cardboard. . .

So far, so good. I didn’t see a specific heating instruction in the original post, so I went with 350 degrees, figuring its always easier to turn the heat up than to try putting out a nail varnish fire. However, 350 was perfect, so I’d go with that if you want to try this.
Now, I’m not the most patient woman in the world, so I used the oven to dry the first coat. I didn’t let it dry completely because I figured a bit of drag would just add to the bubbly effect. Then I put a thick layer over the top. I popped them back in and it only took about 2 minutes, so I would stand and watch until you get the bubbly level you want.

Copying this experiment was easy, and whilst my earrings don’t look as good as theirs I’m at least in the same neighborhood. I reckon they may have used a third coat— and that could look awesome. Also, I think they varnished; and clearly, she’s better at taking pictures than me.
It might be interesting to try this process on metal, for a bangle or a brooch, I don’t think it would come out differently than cardboard, but if the metal itself was warm it might make a different pattern.
Anyway I think it’s neat, and this person— whoever they are— is my crafting god of the week.
Love, Em.
