As for pics, get a photobucket account, upload your pics then copy and paste into your post from the appropriate format selection below your pic on photobucket.
As for DIY blinds, I've been there, done that. The problem is finding the right fittings to go with whatever tubing you choose. The correct tubing would be 3/4" or 1" OD by 1/8" wall thickness aluminum tubing, and the correct fittings would be Kee Klamp fittings or equivalent. By the time you add up the cost of the tubing and fittings, then the appropriate material to cover it with, the trial and error, the sewing time, the this, the that, by the time you are done you'll have something not near as good as the commercially made blind and you won't save a lot of money.
EMT is a nice material for blinds, cheap, light, but you have ONE fitting available, a cast pull elbow. I haven't found any fittings out there other than what's in the electrical department. If you go that route, ditch the set screws on the fittings and zip a self drilling sheet metal screw thru the set screw hole and into the conduit. Otherwise you'll have a mess when it falls apart on you in the dark when you are setting up 30 minutes before legal. (as I said, been there, done that)
Good luck
