Tattoo practice skin is very realistic. It is made of rubber and engineered to closely mimic the feel of real skin. It can and absolutely should be strapped to any part of your subject’s body. Don’t put your tattoo practice skin down on a flat surface like a table or counter when you use it. The obvious use of tattoo practice skin is for beginners to work on it while they are learning. It beats the alternative of practicing on people before you are ready. This includes yourself! There is no excuse for creating bad tattoos, especially when it can be prevented by something as simple as studying your art and perfecting it on tattoo practice skin. If you are not willing to do this, you have no business in the industry. So, using tattoo practice skin must be the best way for beginners.
