Sew a corset

[Maryna Laas]

I wanted to sew a corset, but a friend said that you need to sew bones. What is it and how to sew them?

You don't 'sew bones' as such, you sew channelling to put bones into.  Historically it would have been pieces of whale bone, but nowadays corset boning is made from steel or plastic.
