Just by accident I think I might have a solution. My daughter who claims the OTC bunk as her room doesn't have any curtains for her side windows. Doesn't want them. I have a shower curtain up but it doesn't cover the whold space. So one day I took a couple t-shirts on hangers and put one on each end, using the loops from the old tape, to cover the gap and ensure privacy. Then I got to thinking I could get a buch of hangers and fashion a 'curtain' that way.
