A bottom stacking and top stacking venetian type blind has a fixed headrail containing a tilt mechanism which tilts the lift cords as well as the movingrail and bottomrail, maintains the centerline plane and center of gravity in the same place throughout the operation of the blind, and provides cord locks for the two sets of lift cords. This blind consists of the fixed headrail containing both tilting and lifting mechanisms; a one-piece or two-piece movingrail; a one-piece or two-piece bottomrail; and a plurality of slats which rest on ladders between the bottomrail and movingrail. The ladders are typically made of cord, but the hardware of this blind will also accommodate fabric tape or sheet ladders. There will always be at least one pair of lift cords which control the movingrail; one cord in the front, and one in the rear. The bottomrail will also have two lift cords passing through, one on each side, if it is a single rail; or four cords for a double rail. A preferred embodiment contains an axle driven cord collecion system.
