This is the book I mentioned (in English):
Stanfield - Griffiths "The Encyclopedia of Knitting"
The Twist are mentioned in p74 of the book (p72 of the site) and further.
Don't look to carefully at the drawings, I don't think they're quite right
p149 And further explain how they work with patterns in this book.
And low on p150 the twist-symbols are explained.
The online book doesn't feature the pattern I'm struggling with. Maybe they deleted it for a purpuse
I'll try posting it here:
I hope it is not too big
Not too good on the computer...
