This pattern is for stranded colourwork socks. They are toe-up and have a short row heel.
There are charts included for sizes S, M, & L.
Basic knowledge of colourwork, sock construction and short row heels is useful for this pattern.
You will need 4 different colours of yarn (great for stash busting!): brown, green, orange, and blue. Or any other colours you want to use. :)
