Well, that took a little bit. First of two tiers of petticoat ruffle on. (Ruffle? Flounce? What is language?)
With the aid of the simple block of metal gathering presser foot and a million sewing pins, I wrangled it on the skirt. The gathering foot isn't super precise, but it sure helped shrink down the ruffle enough that it wasn't a horrible battle to pin it on there!
