Step 1: Getting supplies
Also, you need to get 1 ceramic tile for each coaster you want to make. I used 4.25" tiles I got for 16 cents each at my local hardware store.
Step 2: Cutting
Step 3: Mod Podge
While the Mod Podge is still wet, place your comic where you want it to be and let dry. Make sure to rub over the top of your whole comic to get any bubbles or creases out.
