Rare Woodland Mansion loot pattern that adds the stylized Mojang "M" emblem to a banner via the Loom.
Guide
Find a Dark Forest biome and explore it, or use a Cartographer villager's Woodland Explorer Map to mark the nearest mansion. Travel there well-equipped — mansions spawn Vindicators and Evokers.
Search all rooms for chests; the Mojang Banner Pattern only spawns in Woodland Mansion chest loot at roughly a 3–5% chance per chest, so check every container.
Return to base and open a Loom. Place a Banner in the first slot, any Dye in the second, and the Mojang Banner Pattern in the third slot.
Select the pattern preview and take the finished banner. The Mojang Banner Pattern is not consumed, so you can reuse it on as many banners as you like.
Place the banner on a wall or floor in Java Edition or Bedrock Edition. To redesign, dip the banner in a water Cauldron to remove the topmost layer.

Open a Loom and place a banner, any dye, and the Mojang Banner Pattern in the three slots, then take the finished banner.

Yes. Use the banner on a Cauldron filled with water — each interaction removes the topmost layer.
