**Title:** Feature Request: Customizing Capes with Banner Patterns **Description:** Right now, capes are rare cosmetics with fixed designs. I suggest allowing players to combine a cape with a crafted Banner in a Loom or Smithing Table to overlay their own custom banner designs onto their capes. **Why this fits Minecraft:** This heavily expands player customization and lets multiplayer factions, servers, and friends wear matching custom-designed capes into battle. It utilizes existing in-game assets (banners and capes) to create an entirely new layer of personal expression.
