There are a few different types of paper you can use for a button maker, but the most common and versatile type is adhesive vinyl. Adhesive vinyl comes in sheets and can be cut to any size or shape you need. It's also easy to apply and remove, so you can change your design as often as you like. Other types of paper include photo paper, cardstock, and even thin metal sheets. Experiment with different papers to see what works best for your project.
