Fake tattoo sleeve tutorial

I did a thing today where I woke up and decided to make fake tattoo sleeves. And then a friend wanted to know how I did it because she was going to make some today or tomorrow. So I kinda just threw this together. They will be used for a Cecil Baldwin cosplay that I will probably be doing in a few weeks at my local convention.

Please forgive quality, I only have a cell phone and paint to work with.
