I finished constructing and painting the sky and clouds on the backdrops for the Falmouth extension. A few friends requested that I do a video of how I paint my backdrops. So I put one together and uploaded it to YouTube.
In the video I explain the concept of the floating cove to improve the appearance of the corners. This technique has worked well for me. I have not had any cracks develop in my backdrops over the 13 years the layout has been up.
The video was getting a little long, so I edited out the discussion of why I did not cove the corner by the planned balloon camp. There is a window adjacent to that corner. This window is a possible fire escape for the room. So I did not want to block it with a section of masonite I would use for a cove. Solutions that involved a partial cove just didn't look right. So I plan to rely on the Lowe's observation balloon to help hide the uncoved corner.
I have not yet painted the ground portion of the backdrop as that will depend on how I install the 3D terrain.
