I'll try a couple of other stores that are a little further away, just will have a problem transporting 10' long sections of wood for too far so I was hoping that one of the stores near me would have what I needed.
How do you tell if it is kiln dried or not? Nothing I could see indicated drying method.
As to oak or that really nice diy tensioning screen, weight is an issue for me. I don't have a solid wall to work from (large window in most of that wall) so I am planning on either hanging the screen from the ceiling or from brackets near the top depending on final distance from ceiling.
It always amazes me how hard it is to find simple stuff like this in a major city. Everything is either an hour drive away, a big box store with junk, or only deals with large volume contractors.
