I began with very inexpensive tiles from Home Depot. I don't think they were more than 50 cents each. However, the more you spend the better tile you'll get. These tiles were unfinished around the edges so I had to wrap them with ribbon. If you spend a little more you won't have to take that extra step...but I think the ribbon looks nice and will help with condensation.
You can kind of tell from the photo below that the brown/copper paper between the patterned papers is shimmery. It's from a shimmery paper pack I got at Michael's.
Here are the steps I took to make the coasters:
- Cut all papers to size and adhere to each other (not on tile yet). Make sure to use plenty of adhesive.
- Cover tile with Mod Podge (or other sealant) and adhere paper, as well as rhinestones, if you choose to use them.
- Cover paper with Mod Podge. It will look milky at first, but will dry clear. Don't worry, the rhinestones will become shiny again once the Mod Podge dries.
- Do at least 3 coats to be sure your coaster is good and sealed. Let the Mod Podge dry between coats.
- Let the coasters dry several hours, or overnight is even better.
- Adhere ribbon around edges with a hot glue gun. (I found that the hot glue dried pretty quickly, so I did about 2" at a time.)
- Add felt "feet" so the coasters don't scratch any tables (see below).
