The Bamboo Hanging Sign is an interactive block used to display text while hanging from surfaces. It is crafted using 6 Stripped Bamboo Blocks and 2 Chains in a 3×3 crafting grid and can be placed hanging from solid blocks or attached to the side of other blocks. A Bamboo Hanging Sign allows players to write up to four lines of text. Signs can be edited after placement, allowing text to be changed without breaking the sign. Glow Ink Sacs can be applied to make the text glow in the dark, while Dyes change the text color.

Unlike regular signs, the Bamboo Hanging Sign cannot be placed standing on the ground. It is commonly used for shop signs, decorative nameplates, and wayfinding markers. A Bamboo Hanging Sign can be mined instantly by hand or with any tool.
