King Cole Firefly Aran — Jewel Wasp (6579)

Warm, rich and slightly unexpected. Jewel Wasp works through rust orange, burnished copper and old gold over a dark chocolate-black ground, with occasional passages of deep forest green cutting through the warmth. The green is what stops it being just another autumn shade — it adds a proper jewel-toned complexity.

A newer addition to the range and one that's proved popular for larger projects, where there's enough length for the full colour sequence to show its range. Gorgeous in crochet, where the density of the fabric intensifies the copper tones.

Firefly Aran isn't a glitter yarn — there's no metallic thread and no scratch. The shimmer is built into the fibre itself, giving knitted and crocheted fabric a soft halo and a light-catching glow that shifts as you move. Buy your full quantity in one go where you can, and join new balls at a matching point in the colour run to keep the transitions seamless.
