“Urban environments can provide many excellent design inspirations, and external staircases on tall buildings are particularly dramatic examples. This sweater uses twisted stitches and contrasting textures to create the effect of a wide staircase making its way between building levels,” explains Emma Vining. “Each building level and staircase return is highlighted with a stripe in a contrasting shade.” Emma’s sweater is knitted in a hand-dyed wool-silk yarn from Cat and Sparrow.
