A pattern of vertical zigzags makes an impact on this smart sweater from Dario Tubiana. His stranded colourwork design is knitted flat; the neckband is added once the pieces have been joined, and is folded and stitched to the inside to give a neat finish. Dario has used ColourLab DK from West Yorkshire Spinners, a pure British wool which comes in a wide choice of bright and neutral shades.
