How to hang up a curtain easily and quickly resulting in evenly spread clips

CaptionUse 2N + 1, for example, N=4 -> 17 clips.Start hanging up the curtain with the 2 clips at the ends. Divide the remaining 2N - 1 (N=4 -> 15) clips into two groups each having 2N-1 - 1 (N=4 -> 7) clips separated by 1 clip. Pull the curtain downward and outward until the two sides have equal length. Hang the curtain at the middle to the separator clip. Repeat the above process recursively (N=4 -> splitting 7 clips each side to 3 clips separated by 1 clip). In the last round split 3 clips into two groups each having 1 clip separated by 1 clip.If done right, hanging to every clip happens at the middle of an already hanged section of the curtain. Easy, quick and evenly spread.
