This pattern isn't difficult at all, and it's FUN. A slipped stitch with varying solid rows in between allows the yarn to do the work; a simple lace repeat at the end adds some contrast. Only one color of yarn is worked at a time.
This pattern was designed for one skein each of a variegated and solid sock/fingering weight yarn. While of course you can pick and choose your own variegated/solid pairings, we've put together some sets in Yummy 2-Ply to help you out.
You can purchase the pattern for Albuquerque Sunset directly from the designer on Ravelry. All patterns are sold separately and not included with the purchase of yarn.
