Some shots of a double weave sample done on my eight harness Cranbrook loom. A tubular structure: two layers of cloth woven simultaneously connected along the selvedges. The top layer is raw silk and the bottom layer is merino wool (with a much looser sett), both warp. The weft is coloured cotton.
Here you can see both layers of cloth with their connected selvedge running down the center.
Pre-felting, inside of tube.
Post felting: I just tossed it in the washing machine with some towels and the looser merino warp shrunk and felted right up, making the raw silk bubble out.

My original idea was to use double weave to design a new scarf for differential shrinkage, but I think the cloth would just be too thick....But learning and adapting the very basics of double weave has been a great exercise and I have just tapped the surface.
