I just finished my second b-day dress, and on this one I tried a full lining since my fabric was white. It ended up being a lot easier than I expected. I taped the facing pattern piece on top of the side and center pattern pieces for both the front and back and used that to make my own “full facing piece.” It is not at all technically sound, but it worked.
I just used the line of the dress for my sewing rather than the facing piece as they did not line up 100% around the shoulders. I followed the directions for sewing the facing pieces together and then to the dress, and sewed the entire side seam to the entire length of the button placket. I stopped about an inch before the end to allow for hemming and I just serged the bottom of the lining piece (although it could be hemmed) and although I used the facing method with my first dress, I decided to use ricrac for the hem facing since the dress needed a bit more and ricrac was what I had to settle with.
