Pry the plugs out of the bottom rail with a flathead screwdriver. Set the plugs aside for reuse later. If the pull cords are threaded through the plugs, cut them off close to the plug. If the pull cords are knotted inside the bottom rail, cut them above the rail to free it. Slide the rail out from the ladder cords and set it aside.
Horizontal blind slats that hang below the windowsill are not only unsightly but also a strangulation hazard for young children. Most dangerous are the pull cords. Shortening the blinds to the proper height will raise the pull cords and make your home a safer place.
The bottom rail runs through the ladder cords, and the pull cords are knotted below the rail on each end. Photo 1 shows how to disassemble the cords from the bottom rail. The pull cords hang between the ladder cords and lift the blinds up when you pull them. Pull them out and cut off the excess blind slats as shown in Photo 2, then reassemble the bottom rail (Photo 3). If the pull cords still hang low when you're finished, install a cleat to store them higher, out of kids' reach.
