Kerstin Froberg kindly sent me a link for weaving this shawl. I had never heard of this kind of shawl but it is woven with a twist included. Instructions are given for weaving it on an improvised loom which has been clamped to a table rather than used as a backstrap loom.
Here is the link.............www.piening.nl/
MANY THANKS TO KERSTIN.
