Hexagon is a very good decorative theme in tattoos. Hexagon makes the whole design more clean. If you don't know what to decorate when designing patterns, hexagon is definitely your best choice.
Take a look at these hexagon tattoo designs I collected. Do you think hexagon can make the whole design more regular. The next time you do a tattoo design, try to use the hexagon.
