Cedar siding from Hell, oh, I mean Home Depot. Never ever buy their cedar siding. It was cut different sizes and bent and warped and basically a nightmare to put up.

And did I mention how hard it is to stuff a house with sheeps wool? My advice screw the R value and get the batting and just roll it into the walls. SOOOOOO much easier!
