This is truly a beginner vest It is like knitting 6 scarves, then assembling them into a sweater. The Tosca Light is a slow striping yarn. Since all of the pieces are approx. the same width, the striping stays uniform, instead of changing to narrower stripes on wider pieces. The pieces will be easier to sew together if they all have the same number of rows. You will be really great at mattress stitch by the time the sweater is finished.
