I built a table-top jack loom (4 shafts) about 20 years ago, and have just now (!) begun to use it. Have been kinda busy meanwhile. I wish to make chenille scarves for my wife and other relatives. Looking at posts which discuss the use of chenille, I see many references to the term "worming". In the context of weaving chenille, what exactly does "worming" describe? I want to make chenille scarves because they are, without a doubt, the most luxurious material we have seen at craft shows. Also, which would be better, cotton chenille, or rayon chenille? Thank you in advance for any help anyone can give.
