From the book jacket (Interweave Press):

“Add a colorful touch of magic to your knitting with this simple and clever technique. Shadow knitting alternated rows of light and dark yarn to produce a subtle, undulating patterning that appears and disappears depending on the angle from which it is viewed.

This elegant hat and scarf set has an easy-to-knit triangular shadow pattern.“
