You'll need the software on your NookPhone to create Custom Designs. You will be given this at the beginning of the game. Pick the custom designs app by pressing the 'ZL' key on the screen. You can make your own templates from this point on. With 'L' and 'R,' you can change the color of your pencil, and with 'Y,' you can increase the size of your pencil. On the right side of the page, you'll find a variety of choices. We suggest playing with these first; for example, you might add stars, hearts, and circles.
How to Get Rid of the Grid
When you first start your design, you'll find a pink grid on the canvas. It is possible to erase this by painting over it with white paint. You can do so by selecting the fill button, which will provide you with a blank canvas on which to work.
How to Gain Access to Professional Designs
You must purchase the Pro Design update from a Nook Stop in order to unlock Pro Designs in Animal Crossing New Horizons. This will set you back 800 Nook Miles (read all about Nook Miles here), but it'll be well worth it if you're serious about creating your own patterns. The update will be downloaded to your phone automatically.

You'll find new choices if you open the Custom Designs software on your phone after purchasing the Pro upgrade. You can go back to the Pro Designs menu to see what new choices are available. Tops, dresses, and hats are available to purchase. Here, you can use your own custom designs. You'll have more control over your projects if you use the Pro Design options. Simply put, you can draw on more pixels, allowing you to create more complex designs.
