Okay, so I'm making really good progress considering the time constraints I'm working with.
Today, I got the skirt back assembled and top stitched. And I've decided to do something I've never done before.
Rather than sewing front to back and then attaching the waistband, I've decided to attach the back waistband to the back, and the front waistband to the front prior to attaching front to back at the side seams. The main reason I decided to do this is to make my life easier for when this skirt needs to be taken in (if it should ever require taking in).
