There are a few things you need before starting to make stamps in Photoshop. First, you will need a stamp sheet. This sheet is where you will list out the design you want to stamp on your paper. You can either print it out or save it as a PDF. Next, you will need some basic Photoshop tools. These tools include the brush tool, the selection tool, and the layer masking tool. Lastly, you will need some paper. You can either use white paper or any other type of paper that is easy to work with. Once you have all of these tools and materials, it is time to start stamping!
