When I made the DIY Postcard Coasters, I also made two gold glitter coasters with the two extra coaster I had left. I've got both the glitter and postcard ones on my coffee table, and I like the way they look together.
The process for making the Glitter Coasters is fairly simple.
For supplies you'll need: Modpodge, glitter, old coasters, and a paintbrush.
Step One: Apply a coat of modpodge directly to the top of the coaster.
Step Two: Cover the modpodge with glitter. You'll want to have paper underneath to catch the excess glitter. I'd also advise using another sheet of paper on top to press down the glitter. Wait for the modpodge to dry. Then, shake off the excess glitter.
Step Three: Cover the glitter with a second layer of modpodge. Don't worry, it will dry clear. If there are any bare spots, you'll want to repeat the process in those areas. Otherwise, you're finished once the modpodge dries.
Now you can enjoy your new sparkly coaster.
