I've mentioned working on the fabric info thing - and one of the things I really want to include is lesser-known weaves. Well, weaves lesser known today, I should say, because back in their hey-day, things like samite and Rippenköper definitely were well-known.
Rippenköper is something that I wasn't really familiar with either; it only had a relatively short time where it was the Thing (or at least one of the things). It's a twill variation, made by changing over from 2/1 twill to 1/2 twill after a few wefts, which results in narrow stripes giving a pleated effect. Since this is a weave where you will see more of the warp or more of the weft depending on which side you're looking at, if you have warp and weft threads in different colours, it will also give you a colour stripe effect.
If you're curious about that weave now, Carolyn Priest-Dorman has written a blogpost about it a while ago, including a pretty picture of a Rippenköper she wove in the background of the page -
