These coasters look like rafts afloat a tabletop.

22 small, straight twigs
For each coaster, trim 22 small, straight twigs to a length of 5 inches.
Double a length of twine, loop center an inch from the end of first twig, and tie once.
Tie twine around remaining twigs, one by one. Tie knot at end; cut twine close to knot. Repeat on other side.
