Trim the pictures to 4"x4" and wipe down the coasters and allow them to dry.

Apply Mod Podge to the back of the pictures with a paintbrush and immediately stick to the center of the coaster.

Apply two coats of Mod Podge to the top of the picture all the way to the corners allowing the Mod Podge to dry between coats.

Once the Mod Podge is dry, spray with two coats Clear Acrylic Sealer allowing the sealer to dry between coats.
