I can give you some measurements for the driver that are pretty close. The only issue was getting the exact number of holes punched equally spaced to line up with the top line of the side piece.
These are the measurements for my sisters fabric club cover. I think I used like 3-4 veg tan tooling leather so a bit stiff, no real give. It fits my more rounded head driver but you might want to add a bit to top line and round top for the more elongated driver heads
16” top line
14” bottom line
6” top circle
i can post a pic later on. But here’s a blade putter head cover I did too.
