She is an editor at McCalls (I THINK). She has tutorials on there for preparing pieces and often runs a BOM. I think there is an old one on there still : Mimi's Bloomers. Just saw a sneak peak of something on her design wall for an upcoming BOM.
I am planning on working on some prepared pieces for traveling. I DO love backbasting tho!~
