I have mostly finished my bodiced petticoat (for under my voile regency dress I'm planning). It's a pretty simple affair just using scrap muslin from the stash. I started with the Sense and Sensibility pattern, and looking at these instructions I put it together with no problems. It's not particularly accurate, but I think it will work well under my new dress.
The back (it still needs closures, but I couldn't find my hooks and eyes this morning)
