This two-in-one vest makes a great travel companion. On one side, vertical lines of stockinette stitches in the main color float on a garter stitch base, spots of the contrast color peeking through. Turn the vest inside out, and the vertical lines are in the contrast color, with spots of the main color peeking through. The magic comes from working flat on circular needles. You work 2 rows of a simple slip-stitch pattern with one yarn, push all the stitches to the other end of the circular needle, and work two slip-stitch rows from that side with the other yarn. The garter ridge bands that form the edgings and vertical insertions are worked as you knit the vest, so very little finishing is required.
