I finally have pics of the skirt and petticoat I drafted with that Keystone tailoring guide. I'm sorry that they're not perfectly focused; my older sister was acting really rude and refused to take them for me, so I had to use the timer and hope I showed up in the frame. I also have my other three (slightly starched) pettis on underneath in the photos.
Agh! I just noticed the huge mess in the background....
Each flounce on the petticoat is bound with self bias, and the 18 foot hem is bound with store-bought bias. Each seam except the placket seam was serged, then felled to one side and stitched, which saved a lot of time. There's also a 3 inch toffee-coloured taffeta ruffle hiding underneath the bottom flounce.
The skirt needs ironing, and I need to sew a tie at the back to keep the gathers in place. The pocket openings need to be topstitched, as well, and I'm going to have to sew some snaps in the placket opening to keep it from gapping, but other than those minor details it's basically done. I love it, though, it's so dang full. That's a good four feet of fabric pleated or gathered at the center back of both skirts. And it really helps to make it look like I have hips.
The netted hem facings really made a difference in the overall silhouette.
