Description:

Banner Workshop is a placeable block that sells banner pattern charges (Creeper, Skull, and Field Masoned) via an on-screen purchase menu. Place the Workshop and right-click it to open the GUI, choose a pattern and confirm the purchase—iron ingots are validated and consumed, with on-screen messages for success or insufficient iron and automatic refunds if your inventory is full. The GUI also uses a per-player lock to prevent rapid re-opening.
