Yes. I used hdc because it kept the boucle yarn from becoming too stiff.
Yes; I used tunisian simple on the body of the piece and then (because it needed a little something and I wanted very neat edges), I used hdc around the edges with a mohair boucle yarn. In this picture, the ends haven't been darned in yet but it makes for a nice lightweight piece people don't believe wasn't woven.
can this be made in other yarns like cotton??
Absolutely. Sure. I'm making another one in a variegated cotton ribbon. Try a larger hook to get the drape you like best.
