If you already visit the Lion Brand Yarn (Click to view) site to pick up their free Loom-Woven Patterns from time-to-time, you've no doubt seen the Boyfriend Scarf #L10001. (Photo cut from Lion website.)
Well, Dorothy downloaded this one because, as she says: "How did they get that nice weave pattern on a Cricket rigid-heddle loom"?
So, she warped our Cricket and studied what happens when you weave.
It's simply a "Color and Weave" threading.
And… Turns out that back in 2006, the Weavers Guild of Greater Kansas City did a Swatch Exchange, and the pdf they sent out has a bibliography. Here's the link. http://www.kcweaversguild.org/downloads/patterns/color_weave.pdf
