This tank top design from Mary Henderson has a Fair Isle pattern worked in shades of blue and pink, with tiny dots of green providing contrast. Corrugated ribbed edges complement the colourwork. “My design is knitted in Copenhagen Fibers Merino Light, which is delightful to work with,” says Mary. “It is a soft, lightweight wool that knits to standard 4ply tension, so it’s easy to use for any Fair Isle pattern.”
