Finally!

 The siding is one inch strips cut from textured poster board. The poster board is colored all the way through so I don't have any white edges to deal with. I started on the kitchen wall where I closed off a doorway to fit the fridge in.

 Once I had two of the poster boards cut into strips, I got started. It is going well but it's definitely time consuming.

 I love how the white trim pops against the dark blue.

 Now I need opinions. Do I put the hot tub on the deck...

...or not?

I really should call it a night but I really want to finish the siding. Check back tomorrow to see what I do, lol.
