This hat was inspired by the shapes of basalt rock formations such as the Giant’s Causeway in Northern Ireland. It’s knitted in the round, and features a simple colourwork pattern. The hat would work in a solid and a gradient yarn as shown here, or in two solid contrast colours. It knits up quickly, so would make an ideal gift!
