Usually the top and the bottom buttonholes are close to the top edge and bottom edge of the buttonhole band and then the other buttons are evenly spaced between. Eunny Jang has a neat trick where she cuts a strip of paper that is the same length as the length from the top button to the bottom button. Then she folds and uses the creases to mark the other buttonholes. (You can fold as many times as you need to for the number of buttonholes you'd like.)
