There are wonderful things about working with the same people and the same patterns over and over. I'm making a corset for my sister for the Harvest Music Festival in October. She's spinning poi and probably doing some other hippie performing arts (like fire fans and hoop and stuff I can't do). Her group is doing themed costumes, and she decided she wants an underbust corset. I made another for her earlier this year for fun.
Since I have the pattern for her underbust corset on file and I've made this particular style a few times, I cut and assembled the sides within 30 minutes. I have to get more coutil and a busk before I finish each half, but I might just drop in the waist tape with room at the ends and put in some boning channels before I have the rest of the supplies.
