I’ve always been fascinated by illustrations of fan reeds in books. In Japan, I purchased an obi woven with one. I also saw another style which I am calling a “special” fan reed.
The reed must raise and lower to accomplish the variety of spacing. Overhead beaters are ideal. I’m still trying to figure out a way to use one with my underslung beater. At any rate, I do love the wavy lines in the
obi that are caused by the reed. Only a portion of the obi is woven this way; most of it is woven with the wefts going straight across from selvedge to selvedge. Maybe someday I’ll get to my photos from the Japan trip and show cloth woven with the “special” fan reed.
