I have made my first Ren Gown in 2007. This is the Diary of its construction. Most photos are from my cell phone. I hope these note will be of some help to your sewing adventures or lead you to the useful places from which I have benefited. I like to think of myself as a playtron at the Michigan Ren Faires.
I've made one finished effigy corset with tabs and it's too big. I'm going to try it again.
I'm using the Corset Generator from Elizabethan Costume.net.
