Any advice on aftercare while getting a back piece?

I'm starting my back next month and have started wondering how I'm going to handle the healing process. It's likely going to done over 5-6 sessions over 6 months. I have 12 tattoos, none took more than a single session.

Usually I leave the original wrapping on for a night or two, clean the skin, then cover in tagiderm for 2-3 days if I can. How is it this possible when you're outlinging/shading your entire back?

Any advice greatly appreciated. TYIA!
