1. Use yellow ink to color around two square coaster; glue yellow card stock to both sides of the coaster; cut around each corner to match the card stock to the coaster.
2. Attach two clothespins on the back of one coaster using double sided tape (foam). I stacked two small pieces on top and three on the bottom. In the picture below, I used two on top and one + rubber stamp remnants (w/o the rubber) on the bottom.
4. Cut a card stock 3 1/2" x 3 1/2" and another card stock (of coordinating color) 3 3/8" x 3 3/8". Glue them onto the coaster.
5. Add whatever design you want to the front of the coaster.
Doesn't that sound so simple? Yet, it took me a long time. Enjoy.
