This Hat is named for Hecate, the Greek goddess of doorways and crossroads whose three bodies moved as one. Hecate is a jigsaw of connected cubes, working together to create a beautiful pattern from simple shapes.

Each Hat in the Imperceptions collection is knitted bottom-up and in the round. The ideal yarn for these Hats is 4-ply or light sportweight, in a multi-plied fibre with some natural give, such as merino. The illusions look their best in two high-contrast colours. Available as a single pattern or as part of the Imperceptions collection.


Hat Description

Hecate is a slouchy stranded colourwork Hat worked from the bottom up in two colours. The colours are equally weighted in the pattern, using single stitch and single row patterning. It starts with a corrugated rib brim that feeds into the body pattern. The body pattern creates an optical illusion effect of wide diamonds all the way around, created by interlocking nested squares. The crown shaping continues the pattern, creating nested triangles that point towards the centre.
