Unity is created in the coaster in the foreground through the use of the circled edge. This simplistic design achieves unity as the circular holes ties together the circular ideas presented by the overall shape of the coaster.
The oversized buttons are made out of wood in a rustic, pale wood finish. They are tied together with a large piece of string. A perfect little set to give as a gift. The Button Wood Coaster comes in a lovely set of 6 pieces.
