This is another scarf from the book, Scarf Style. It is called Zigzag Stripes, though there are no stripes in this version. The yarn doesn't do much to show off the zigzags; therefore, dingle balls were installed.
The lovely model is Dave's mom, Carolyn. The Spanish word for mother-in-law is la suegra, though my dad, the first Mexican I ever met, used to call every mother-in-law "the barracuda".
