Heart and Sole 4 ply is a stripey, self-patterning sock yarn. This fun yarn comes in a range of the most eye-catching colour combos. Each 100g ball has a free sock pattern on the ball band and will make one pair of socks on 3 ¼ mm needles. Heart and Sole is a brilliant yarn for exploring colour, and although it has been designed for socks it is also great for smaller projects, such as toys and accessories. It has a sturdy blend of 75% wool and 25% nylon, making it an extremely durable yarn. Heart and Sole is machine washable and cool tumble dry. Note: If knitting the sock pattern, the suggested needle size is 2.75mm, and is written for shoe sizes 4-6 1/2 .
