Palette House is the custom creation workshop in Tomodachi Life: Living the Dream. It lets you make clothing, food, pets, treasures, wallpaper, house exteriors, island objects, and other custom designs by drawing them in the in-game editor.
The truly difficult part is sharing and drawing from references. Palette House does not have universal online import codes like Animal Crossing or the old 3DS games. When you see a design you like on social media, you usually cannot scan it into your game. You need to redraw it by hand in your own save.
That is why this site prioritizes pattern sheets, full grids, clear screenshots, and source links. After careful screening, scattered player posts become references you can actually follow.
