Measuring route holes for replacement slats
From the left to right, measure from the end of the slat to the center of the 1st hole.
Then measure from the left end of the slat to the center of 2nd hole.
Repeat this step for all the routed holes on the slat.
For routless blinds, measure the same way to the center of the notch on the slat.
