How do u even make stamps???
Stamps? Well I usually find a stamp template or I make my own background with the pixilation of the stamp template. Then you just use your photo editing or other another software. You then edit it directly from there. If you want them animated I use ezimba frame animation and edit it frame by frame and save it as a gif to my computer. Otherwise for non animated you just save it regularly. Just submit it to deviant art and you're done! There's plenty of other tutorials that would probably sum it up better.
