I *think* I may have figured it out. Broke down last night and just decided to fold and pin the pleats to get a good visual of what was going on. Turns out, my pleat marks were WAY off. When I did it to what looked right to me I ended where I believe I should be. I've attached a picture to hopefully help illustrate. But I've got 12 pleats either side of the center pleat so that was good, but do they begin and end as they should?
