Since you are painting it, you don't need to be picky about appearance.
Almost any wood that had been Kiln Dried should be OK to use. Maybe you can
find something in the Molding isle at the hardware store or lumber yard.
You could also rip the pieces off of some Shelfing stock.

Poplar would probably be a good choice but most woods are stable once
completely dried, especially once sealed with paint. Red Oak would also
work well, as it is harder than poplar and may be stronger considering 1x1
construction (which I question but will ignore that since I can't look at
your actual idea). Less likly to split from the fastners or crack along the
grain.

Hi all,
I'm looking to build a room divider 6 feet high by 18 inches wide,
using 1 inch by 1 inch wood. The plan is to paint the frame white, and
fill in the frame with wallpaper. Can anyone recommend a good wood
species that will stay true and not warp over time?
Thanks in advance for your help.
