With Estelle Sock Twins Brights, you can knit a matching pair of socks. With 4 multi-coloured plies that change colour over time, these gradients are smooth and come in a wide variety of bright, bold colours!
Sock Twins come in a kit which contains two balls that slowly change colour, while knitting up the same so you end up with matching socks.
Each kit comes with 2-50g balls with 200m on each ball for a total of 400m. It's a blend of 75% superwash wool and 25% nylon in a fingering/sock weight.
