LolaT, did you figure out the facing? I made a size 116, and it fit perfectly. I'm wondering if you expected the facing to go to the back edges though. This facing attaches to the back edge that is folded back on itself .... so the facing is an inch or so shorter on each side, and the fold back forms part of it. Clear as mud? Let me know if you are still confused and I'll snap a pic of the inside.
