So here's how I conquered the eggshell coaster. It's a tad bit different than what Adrianne did, but I was trying to use things I had on-hand so I didn't have to make a trip to the store.
You'll need the following things:
2. Clear Glass Tile
3. Piece of Cork
4. Mod Podge Dimensional Magic
5. Ink (I used India Ink because that's what I had, alcohol ink is much cheaper, and can be found at Consumer Crafts)
7. Hot Glue Gun
First, you want to make sure all of the membrane is off of the eggshell. Adrianne provides some helpful tips on this here.
Next, I put a decent amount of dimensional glaze on the bottom of the coaster and began arranging my shells. Because I was arranging my eggshells on the bottom of my coaster, it wasn't imperative that my eggshells lay neat and flat on the glass. However, if you want to do this so that the dimensional glaze and eggshells are your coaster top, you'll need more glaze and you'll want to make sure your eggshells lay flat.
I let this dry overnight. Then, I attached the piece of cork to the back with some hot glue. And there you have it! A pretty coaster!
