I screwed up a bit on this tutorial because this skirt has a full lining. So, pretend the lining fabric is sewn to the bottom of the facing. Cut the SA off the facing but not off the lining. I usually make a little pleat on both sides and keep that extra ease in the lining piece.
Remember that there is lining on the bottom of the facing piece. You would continue doing this all the way to the bottom of the zipper.
After I attached the facing, I did go back and attach the lining. You can do it either way but I usually put the lining on the facing first and then attach the facing. I'm not sure why I did it differently this time.
