I've woven a little sample blanket of the lampas weaves I've been using, but with new weft yarns. The ground weft is a gray cotton, and the two pattern wefts are a cream colored bamboo (not strange) and an olive green polyrurethane coated cotton (very strange). I've had the latter yarn in my stash for a while, and don't remember where (or why) I bought it, but thought I'd try it out. This might be a good fabric for a book cover. It has a stiff, plasticky feel.
