The lining is Liberty of London print backed by a layer of thin cotton batting. It closes with a hidden magnetic snap.
There is some minor wrinkling next to the left pleated, which is where I pieced the interfacing together (all I had left was scraps!), but didn't quite overlap the edges well enough.
Anyway, it's not very obvious, but I like to tell you when things go awry. I guess the moral of the sewing story is it's ok to piece together interfacing sometimes (small things), but make sure the edges overlap!
