LMBO. You guys are killin' me.

...Only because I can sympathize with you to an extent. If you think the Doghouse and Penthouse are bad then try putting their umbrella back into its pack. The blinds are a cinch by comparison.
Getting the blinds folded up again does take some practice but once you learn the trick to it then it almost becomes subconscious. After the blind is flat and you are again folding it "in half" then bend your arms together at the wrists and just let the blind layer one on top of the other. The spring steel almost guides you at that point.
