Sharing

To unlock the feature in, the player must first befriend Sable who will bring in a new sewing machine that will allow them to create and read QR codes. In, the machine is available in the upstairs of Nook's Homes after completing the lesson "Even More Designs" in exchange for 5 Play Coins. QR codes are stored as images on the SD card inserted into the Nintendo 3DS. Normal designs use one QR code, but pro designs are comprised of four separate codes. Once the codes have been scanned, a slot must be selected for the design to be saved to.

is backwards compatible with QR codes created for these previous titles via the NookLink service of the Nintendo Switch Online app for iOS and Android (Face-cutout standees can only be imported after an update following the release of the 1.9.0 Free Update). The app can scan valid QR codes, saving up to one design at a time and overwriting any previously scanned design. The player must then select the Download function of the Custom Designs NookPhone app to import the design from the app into the game itself. Imported designs retain the formats used in, which have different appearances and dimensions to the changed formats used in. Importing a Horned hat pro design from is the only way to obtain this style of headwear in. Although introduces the ability to apply custom designs directly to a character when remodeling their home, designs that were imported from a Nintendo 3DS title cannot be used.

Designs that are created in can be shared after befriending Sable once again. In this game, shared designs do not use QR codes. Instead they are uploaded to Nintendo's servers and can be shared with other players by having them input an alphanumeric code. A Nintendo Switch Online subscription is required for this service.

In all games, imported designs cannot be modified. The metadata for each design contains the author's name, their town name, and a hidden identifier. Should this metadata somehow match that of another player, the game will treat the design as if it is their own and allow them to modify it.
