How to use qr codes as wallpaper?

[Mayor of Uncia]

I've seen tons of pics online of people using qr codes they made as wallpaper in their houses.
HOW DO??!?!?
Whatever I type in google I just get more qr codes and people asking how to use them, but no one has any information!!

When you're in your room, in the bottom screen you'll see a couple tabs (where your Inventory/pockets is). Click the one with the pink pencil where you QR codes are kept. If you click the QR pattern you want as the background, Click the option that says spread in room. It will give you the option to use on the wall or on the floor, you can even have it rotated which makes some patterns look a little better sometimes.

Oh my glob, thank you so much. I was having a minor breakdown because my google-fu was letting me down.

Well, first of all, do you know how to get a qr code?
Here is how: https://www.google.de/search?q=how+to+use+qr+codes+in+acnl

Once you have a qr code, go to the room where you want to use it as wallpaper. Click on the pattern you want to use, then make your choices from the list.

I knew that part, but thanks for posting that in case someone is looking for these same answers and doesn't know. x3
