There are a few different ways to create basketball clip art. Most graphic design programs include some way to turn a picture you want to make into a piece of clip art. The exact steps vary from program to program, but the general concept is to start with a photo or drawing of a shape that has the same general outline as the piece of clip art you are trying to make, and then use semi-transparent shapes and drawing tools to trace the lines and add detail. You can also download high-res images, or explore additional basketball clip art and vectors for more options.
