I taught a workshop on this subject last week at Convergence, the biennial conference for the Handweavers Guild of America, held this year in Reno, Nevada. "One Warp, Many Structures: An Exploration of Extended Parallel Threading" looked at all the possibilities I mentioned above. To teach this, I designed 9 different patterns -- 3 for 4 shaft looms, 3 for 8 shafts, and 3 for 12 shafts -- and invited students to choose a pattern and wind a warp using two colors of 10/2 pearl cotton. (I also named all of these patterns, using simple descriptions as a mnemonic device -- otherwise I couldn't remember them all!)
Below is a photo essay showing some of the beautiful samples the folks in my workshop created, with brief descriptions for each. It was a visual feast!
Above on left: Echo Weave sample using 8-shaft pattern, "Many Rivers," in light blue and off-white warp yarns. On right: the same pattern, this time in Double Weave, with top layer woven in off-white 10/2 cotton and bottom layer woven in 18/2 merino. The bottom layer fulls with hot water, soap, and agitation, making the top layer collapse and pucker. Woven by Roberta McKinney.
Woven by Judith Rees.

The two photos above: front and back of the "Falling Stars" pattern on 8 shafts in Double Weave.
The warps alternate between a golden yellow and a hand-painted yarn in shades of green and blue. Woven by Sharlet Elms.
The two photos above: front and back of collapse cloth in the 8-shaft "Falling Stars" pattern, woven as Double Weave. The weft alternates between 10/2 cotton in gold (front) and 18/2 merino in purple (back). With washing, soap, and a lot of agitation, the merino fulls on the back, making the layer on the top collapse into pleats. Woven by Sharlet Elms.
"Many Rivers" design woven on 8 shafts. Pictured from top to bottom:
Echo, Shadow Weave, and Jin. Woven by Virginia Glenn.
Pictured above, clockwise from top left: 8-shaft "Falling Stars" pattern in Shadow Weave,
Double Weave, Rep Weave, and again in Double Weave. Woven by Ruth Ronan.
Blooming Leaf pattern on 4 shafts woven as Jin. Woven by Sharolene Brunston.
Above, top to bottom: "Fun House" pattern for 8 shafts. The top two samples are woven using a different Echo tieup and treadling from the bottom 4 samples. The bottom 4 samples are all the same tieup and treadling for Echo, but using different colored wefts. The warp yarns are light blue and turquoise. Woven by Carie Kramer.
