1. Remove all but the top layer of the napkin. Keep the other 2 layers as you will need them, too. Select the motif that will be seen on the coaster. Paint underneath the coaster with the glue and carefully place the top side of the napkin onto the glue. (So the “good” side will appear from underneath the disc).
2. Smoothen out any wrinkles with your fingers and apply a second coat of glue onto the napkin. Let it dry thoroughly.
3. Because the napkin almost seems too transparent, apply glue again and now adhere one of the white layers onto the napkin. Smoothen out the wrinkles and then apply a second coat of glue onto this layer.
4. If you still feel it is too transparent, repeat step 3 again with the other white layer of napkin. Finish off with a coat of glue and let it dry thoroughly.
