There are a few ways to make a design on Figma. The most common way is to start by creating a rough sketch on a piece of paper, and then importing that into Figma.
Once your sketch is in Figma, you can start working on your design using the tools available in the software.
One of the best ways to learn how to use Figma is to start by creating a simple project. You can find a few example projects on the Figma website, or you can use the online tutorial.
Once you have a basic understanding of how to use the software, you can start to create more complex designs.
