Fast forward to six months, I decided to tweak these coasters.
I had this gold scrap book paper that I had used for some other project. It is a pretty thick paper. My plan was to modge podge the gold paper on the top, paint the rim of the coaster either red or gold, both of which I had.
I applied Mod Podge on the top of the coasters with a brush. Placed the gold paper on the it. Once I was done with the Mod Podge on all the coasters, I placed heavy books on them and left so overnight.
