So, I had to paint the back entryway, which has a set of stairs to the basement. I had to paint the ceiling, including the part above the bottom of the stairs, which was a pretty serious reach. The extension ladder was too tall, and the a-frame was almost tall enough.
Double ladder! Always a good idea to balance a ladder on another ladder. Never the wrong choice. But it worked. And the ceiling got painted, and it looks much better.
I learned some other things too. I already knew that you shouldn't paint yourself into a corner when doing floors, so I didn't make that exact mistake. But I may have glued myself in.... just a little bit.
With way cooler kneepads.
