Always put your thoughts on paper. It's immensely helpful not only for working through your design, but also as a way to communicate with the hardware store staff who may or may not have any concept of what it is you're trying to make.
Because I didn't need the fabric to be easily swapped out, I modified the original photography backdrop build to directly incorporate the fabric part, rather than having it draped over the top. I really liked the idea of being able to take it off and roll it up though as that seemed super portable, so I intended to preserve that ability.
I also made one on-the-fly change in the store which isn't drawn here- I raised the crossbar, so that some of the height was part of the 'feet'. So the total vertical height is split into one long piece and one shorter piece. (later in the build I also figured out that I'm too short to actually grab both sides of a 6ft wide panel at the same time, which is kind of necessary to setting it up. So I had to cut the horizontal pieces again. To save you time, I'm going to pretend I got that right from the beginning. )
One Freestanding Visual Divider:
2 5ft lengths of 1in PVC pipe for crosspiece
2 6ft lengths of 1in PVC pipe for vertical
6 1ft lengths of 1 in PVC pipe, four for floor support, two for height
4 1 in PVC endcaps
4 3-way 1 in PVC joints
2 45 degree turn 1 in PCV joints
PVC cement is optional. (Because I want mine to be able to be disassembled, I didn't use it.)
1 long bolt of heavy-duty cloth, 5+ feet wide, and at least 7ft long. (Later there will be a visual aid and more explanation of this, but suffice it to say that it will look better if the cloth is significantly wider than the crosspiece. If you're at all unsure, remember you can always cut down the PVC with a handsaw. Cutting the cloth and giving it finished edge again is much harder. If your chosen fabric does not already have finished edges, make sure you account for the width that will be taken up by folding them over when making your measurements.)
If this costs you more than $100, you've been had.
