There's a book "Dentelle de Normandie", by Florence Quinette. There are 4
very good pictures of bobbins, one picture showing noquettes covering the
thread.
The book is in both French and English. There is at least one copy
available through Amazon, and Holly Van Sciver carries it.

Dear Brian,
This is a book I was trying to find some years ago. I was told a book
seller in Australia stocked it. However
my search did not succeed. You are in Australia, and may have more luck.
I've changed the Subject line, in hopes it will trigger someone's memory,
and be sorted
