To build a trivet:
1. Arrange five wooden chopsticks together to make a large base hexagon, leaving about an inch between their ends.
2. Starting from the center, glue chopsticks on top, placing them at varying points as you go. Once dry, hot-glue smaller chopstick segments onto the bottom of the trivet (loosely following the original hexagon shape) for reinforcement.
3. Coat with a layer of glossy yellow spray paint. Let dry.
Make the design even easier with a square "grid" trivet at the base.
