Tattoo sleeve template

I plan to get a sleeve done somewhat soon and I realized there aren't many templates to go by. I did find one designed by shown here [link] I tweaked it a fair bit since what I'm planning on getting would be more easily understood in this format (personal prefence of coarse). The measurements are pretty darn exact for the amount of skin on the underside given the variations in the thickness of your arm. And you should be able to strech or squeeze the image to fit your own arm's size. I'll quit babbling... Hope this helps.
