Hiya,

I used to have a darkroom in 2 garages. One time, I just draped black painters plastic to make a "room". Another time, I just did it at night with the doors closed.

This time, I want to make a "temporary" wall.

Would these be good enough:
1x2 wood to make a frame from ceiling to floor
1x2 wood in about 3 feet intervals
1x2 wood in between the 3 feet
then cover it up with the painter's plastic.

I don't need complete darkness. Just dark 'nuf do work at night time. One side will probably be open and that side is the opposite of the garage doors.
