QR codes can be used to share designs with other players in Animal Crossing: New Leaf and Animal Crossing: Happy Home Designer. In the former game, the player can do this by first becoming friends with Sable, who is located at the Able Sisters. Once the task is accomplished, a green sewing machine will appear right behind her. If the player talks to Sable, she will ask if the player would like to create or scan a QR code. If the player chooses to create a QR code, they can select one design to have a QR code made for it. If the player scans one, the player will receive the design from the scanned QR code, which will be placed in one of the player's pattern spots. In the latter game, the player can purchase the 'Even More Designs' lesson for 5 play coins. It unlocks the sewing machine, and the player can use QR Code patterns for their custom designs
The player can import designs to Animal Crossing: New Horizons by scanning QR codes using NookLink in Nintendo Switch Online app. This is the only way for the player to obtain and use the Horned Hat custom design.
These designs were made exclusively by Nintendo or a Nintendo-related company.
A design based on Cat Peach from the Super Mario series.
