I cannot directly answer this question because professional and DIY tattoo stencils are both argumentative. But here is what I can tell you to make a decision. Some people learn how to make a tattoo stencil and do it as a pastime, but many do it as a profession. If you can do it right, you can establish a lucrative and potential business model. In addition, tattoo designs are becoming increasingly popular today. So, if you get it done by a professional or do it yourself, you will undoubtedly stay in the trend. Therefore, you need to focus on the design selection because it should be something you find precious enough to be a part of your skin. Finally, DIY designs have a lot of options. They give you the freedom to be creative. As long as you can make it correctly, you should not let go of the idea.
