Hexagonal plant spacer

NOTE: units are inches, not mm.

A gadget for spacing seeds evenly across a garden bed. It's hexagonal to fit a few more plants into the same area compared to a square planting grid. Planting in every hole will give 1.5" spacing between plants, and planting into only the taller holes will give 3" spacing. The circles are big enough to poke a chopstick through in order to make planting holes for small seeds. I plan to use it for carrots and beets.
