Mrs. D, did you figure it out? You're doing short rows, so it might help to look up some short row tutorials if you're unsure of what to do.
I finally finished mine!
It's the size small with a few modifications (extra hip increases), and I used 8 balls of Pegasus from www.elann.com
. I had to do an extra lace repeat in the center to get it to fit, because I think I chose the wrong size, but it worked out!
