I know it is summer but I love working with Bernat Blanket yarn. I finished this afghan made from Pumpkin Spice. The pattern is free from by Jess Coppom. It is called The Snow Drifter Chunky blanket. You can find it here on the Make & Do Crew webiste.
She gives you guidance on how to make various sizes of blankets. I made one a little bigger than the pattern. I started with ch 112. I ended up using 4 skeins and continued in length until I used up 4 skeins. It turned out to be a nice size. The pattern is easy to follow and works up fast.
