This Blanket pattern is a guide for making a Basket Weave blanket using un-spun chunky wool (wool roving) supported by addition of the industrial yarn.
You will need 13.3 punds or so of wool roving and about 7 oz of yarn in corresponding colour.
The yardage shown in this pattern title is a good guess.
The pattern has many detailed photos to help with tricky points.
