Holy. Crap. Making a petticoat - like a serious multi-layered and multi-tiered - is a substantial feat.
I have been working on one to pair with my Butterick 6582 full skirt dress. The best tutorial I found was by Sugardale : she doesn't post as much as she used to but her petticoats are to die for!
