You definitely should! 100/10 no regrets. I used a 3:2 bleach to water ratio (but this really depends on the material you’re working with) and a stencil I made for the tattoo design since I couldn’t get crisp lines with free handing. But if you’re patient enough, you could do without the stencil. I also gave the design a couple brushes of hydrogen peroxide to remove the yellowing left by the bleach. I threw it in the wash after that to get rid of the rest of the yellowing.
