Fun, natural yarns

[meliaec.livejournal.com]

Does anyone know where I can find yarns that are fun (like Boa, eyelash, fun fur, twister, cha cha, etc.), that are made of natural fibers (silk, rayon, cotton)? I looked at so many yarns at both Michaels and Joanns and the I found maybe one type of yarn that was just a plain sort that was 100% cotton. I would like to find something fun to dye with my procion dyes.
