Place the stencil in the middle of your wood slice.(You can also tape it into place with painter's tape if you're worried about it moving.)
Dab a foam brush in some paint and then dab off any extra so you only have a small amount of paint on your brush.Gently press the paint onto the stencil with an up and down motion, making sure you don't get any paint outside the stencil.
Remove the stencil carefully and let the paint dry for at least 20 minutes.
Step 3: Seal the coaster
Spray the top and bottom of the coaster with a clear sealant. Be sure to do this outside or in a well ventilated room.We did 3 coats on the top and 1 coat on the bottom. Let each coat dry before applying another one, following the directions of your specific sealer.
Step 4: Add table protection to the bottom of the coaster
Once the wood slice is completely dry, add four sticky felt feet to the bottom of the coaster.
