The Mini Sign is a craftable Structure in Don't Starve Together, introduced in A New Reign. It is located in the Structures Tab and requires a Science Machine to prototype. 1 Board is used to craft 4 Mini Signs. By placing an item near a Mini Sign, the player can draw that item on it once by using a Feather Pencil.
Unlike other structures, Mini Signs cannot be destroyed with a Hammer to return their crafting resources, but can be dug up with any kind of Shovel. Digging them up will not remove images that have already been drawn on them. Mini Signs can be used to sort Chests in the players' base, as they can be placed very close to them, or just as decorations.
