“This design was inspired by the geometric shapes of the shell creatures that live in the sea, along with schools of fish swimming in the oceans and the sea turtles which live to great ages,” explains Mary Henderson.

“The jumper uses all my favourite shades of blue, plus some green and pinks to set it all off! Thinking of the sea is good for the soul.”

Mary’s top-down seamless design is knitted in Jamieson & Smith’s Jumper Weight Shetland wool.
