Abstract
A method of shortening the width, that is, sizing a mini blind to any specified dimension by an operator having the skill level found in a retail outlet, is disclosed. In addition, a machine for sizing a mini blind to any specified dimension by an operator having the skill level found in a retail outlet is also disclosed. The method and machine are applicable to mini blinds which require either one or several ladders to be affixed to the blind and hence the operation of one or more drill systems, the number being proportional to the width of the blind.
