Felt is another excellent material to make coasters with
Felt has become a pretty trendy material to work with. Felt balls, in particular, can be found in any crafts store and are ideal for those who want to put together a colorful decoration that can serve as a statement. Simply grab some plain cork coasters, a glue gun, and as many colored balls as you need.
Glue the felt onto the cork base, starting from the center and moving outwards in a spiral shape until it is completely covered. You can easily match the colors of the little balls to your mugs or the style of your home.
