Yes chenille is very difficult, at least some brands. It doesn't have that stretch the way wool or acrylic does. And after it's knit it kind of twists up, it's called worming. Thicker chenille on small needles might not be quite so bad. If you can get a small amount of what you're planning and try it out, I would suggest you do and decide how it's going to work.
