The number of skeins for a blanket depends very much on the size you want to knit and the type of wool.
If you want to knit something with the chunky Peruvian wool "The Wool" in a certain size, we recommend four or five skeins. In our collection we recommend the blanket Udon Blanket with five skeins. If you are looking for something bigger and warmer, check out our Udon XXL, with 9 skeins.
You can also knit something smaller and softer, for children, for example. For this you need two or three skeins of cotton or another, finer wool. In our collection we recommend the Bee Blanket, which is knitted with three skeins of our Pima cotton, or the blanket Dragonfly Blanket with only two balls of Pima cotton.
