A bit of a funny story.
I have to do some regular online Zoom work. I finally bought a small retractable green screen that fits on the back of your office chair to block out the background of your room. It came in a canvas bag, and when you pull it out, it springs to full size. It looks and works great. But when I went to store, I realized I had no way of knowing how it goes back to the small size, and no directions were enclosed.
After some investigation online, I was able to figure out how the bendy metal frame "folds" back into the small storage size. Fun!
