I have this really interesting and helpful device that belonged to my mum. It's called a Tailor Board manufactured by June Tailor, Inc. It's a pressing board for facings and collars and such.
My mum had it for years but I never bothered to use it. I now realize that it's perfect for doll making. They were/are quite pricy but if you ever get a chance to pick one up at a garage sale you won't regret it. So handy for pressing all those awkward seams.
I know she doesn't need knickers because no one will see them but I like the idea. One of my favourite witches is Nanny Ogg from the Discworld books by Terry Pratchett.
I love Nanny and her knickers.....LOL
