I am teaching new weavers who raise Alpacha and are interested in weaving rugs with the yarn from their flock. Rugs are not something that I have made a lot of, so I am seeking some ideas. What might be good weaves for a beginner who wants to weave rugs? Any words of wisdom about weaving with Alpaca? (They intend to mix the fibers with wool.) Any books that are good that you would recommend?
