Hi- I’d like to make a four- poster bed frame, capable of supporting curtains on all 4 sides, but not the roof. I’d put horizontal poles around it at the top and bottom (on floor), and a crossbeam support top/bottom for added stability.Poles can be metal or wood. My skills are limited, so looking for ‘lock together’ type poles and 4 way elbows. Are there any ‘ready to go’ kits I could use? Many thanks! Judith
