If it helps, you can think about it like creating a tarp in reverse. Normally you'd cut the fabric first and then arrange it into the design you want. This simulation allows you to pick the design you want first and it will produce the fabric pattern for you. The way to design the tarp is through cells B2, B3, B4, and B5 in the spreadsheet. With the exception of point O, none of the points in the diagram are dragable.
