The curtains open and close without any problem.
Here's the finished curtains I made out of Kodachrome slides! The slides date from the 50s and early 60s, and are all from a lot of slides I got in Kansas City last fall. The majority of slides on the right panel are of horses. Go figure. Travis drilled 8 holes in the slides using a Dremel tool in a Dremel drill press thingy, and I conntected them all using aluminum chainmail rings.
