Talking about this curtain?:
It was made from 5' wooden poles and the metal ends are lag bolts screwed into the bottom of the wood poles and then the ends of the lag bolts ground down to a point.
The curtain material is the stuff you use for sunrooms. I found it at Home Depot iirc. I used liquid nails and also a staple gun to attach them to the wood poles. The center pole is not attached so that it can be placed at any point between the outside two. I never really worked out how to attach the middle one to the curtain and if you look in the last picture, you can see it attached with a pair of Vise Grips. lol
