They had a loom set up with ikat in process, also showing how the threads are tied for dyeing.
Some of the textiles on display had elaborate patterns, like this wrap from Indonesia (ikat on the warp only).
This robe from Uzbekistan, from the late 19th century, has ikat on its silk warp but not on the cotton weft. The process was elaborate: wind the warp on a frame as if to weave; mark the pattern and tie the threads into bundles; dye, rinse and dry; repeat for each subsequent color.
I loved the way this Uzbek vest was finished.
