Changing the Background in Animal Crossing

I know there are people who don't know this cool little feature in Animal Crossing. Hell, i figured it out by accident. So if i didn't know it was there, there MUST be others who don't know.

Go into your inventory. Grab a Design(pattern) and swing it over to the left corner at the bottom of your screen. A green cursor will show up when it's aligned correctly. Now drop it. The inventory background changes to the pattern you dropped. I tried it with a shirt too and it works.

PS. Gracie told me i look FAB and that i think similar to her. Then tossed me a butterfly shirt.

Peace y'all
