Do I need to add blue squares to this blanket? I can't decide. Little by little I have been cutting out the 225 4"x4" wool felt squares required to make a blanket. Last night I finally laid out all the squares. The directions for the project are found on purlbee. I bought the wool felt for this project almost 2 years ago. It feels good to get this far with the project. Now all I have to do is sew the squares together by hand. No big deal! Phil thinks it will take me all summer. He might be right.
