However, we set up the cards as part of our loom so the edge band was woven contiguously and seamlessly with the cloth. I didn't take a photo but the cards are behind the beater bars. So it's step on a treadle, reach and turn the cards, throw the shuttle, beat twice and repeat.
Card weaving was predominantly done in Ancient Egypt, Scandinavia, Medieval Europe, Asia, and the Middle East. Inga mostly talked about the the work of Iron age Scandinavia. You know, Vikings. The reason I took the class. Here is a site that shows the warp weighted looms they used and some talk about fabric and card weaving. Instead of rocks we weighted the backs of our looms with plastic bottles full of water.
The class samples showing the eleven embellishing techniques we learned. Velvet, several kinds of beading, brocade, tassels, split work, and a few more. While I spent three long, careful, days at it I haven't been bothered to take photos of my incredibly beginner work.
However Inge's work is a whole new level.
