Yarn 
A note on yarn: Each Nutiden colorway is unique in its own way which means that the yarn weight/ yardage might differ from one plate to the next. For this reason, it is really hard to estimate yardage for this pattern, so an approximate yarn weight has been offered instead. In terms of yarn substitution, Plötulopi is probably the closest yarn that you could choose, but you might only need one strand of it to get gauge. 1plate of Plötulopi is enough for this pattern
