Really basic question

[Gayle]

When the directions call for buttonholes to be worked into the stitching,am I correct in thinking thatyou measure from the top of the first one to where the next one should be? Also, when measuring, do I place the ruler end just under the needle, or on the top edge of the needle. I know that I am probably making this too hard, but I do tend to exhibit obsessive compulsive traits from time to time
