A spectacular pattern of gridlines is worked over this jumper by Mary Henderson. It uses three shades of Scheepjes’ Metropolis, a smooth merino-nylon 4ply. “This yarn gives a soft drape to the fabric, so it can be worn next to the skin or layered over a blouse or T-shirt,” says Mary. Her loose-fitting, boxy design has cropped sleeves, and the lower back border is longer than the front, with split hems.
