I made this shawl as an experiment, to see if it would work. I had seen it in a book on weaving. I made a frame that was about 5′ x6′. Then I hammered many nails into the top and bottom of the frame. These nails were used to wind the wool warp on the frame. Then each warp string is cut and woven across the warp. This creates the triangle shape. Thus the warp is the weft. The yarn that I used was included when I purchase my loom.
