Similar to the eyebrow lights, I used the 'score-n-snap' technique to get the straight parts of the skylights done. Then a new 2.25" hole saw (to be used for the instrument panel) was used to get much of the material out of the corners. Using some snips, I liberated the remaining material and folded along the straight portions to snap of 4 sections.
