Do you worry about what to do with the extra mini-blind cord? It is dangerous to young children.
When I purchase a new mini-blind, I move the bell up 16 inches and tie a knot. Then I cut off of the extra cord.
Mr. Frugalfish came up with another solution. He takes the cord over the top of the blind and lets it hang down the other side. That way the cord reaches just the bottom of the window.
