This post has been long overdue!! I made these two blankets LAST Christmas! The red for my brother and the blue for my dad :) I think they turned out great! I found the how to on a tutorial Here!! I honestly think that her blanket turned out much better :) I would definately suggest using only wool sweaters. I used whatever I could find but I found that the 100% wool worked best. I will admit they are harder to find, but it is possible!
I also did my edges a bit different and I will show ya how I did that in a bit! I used 1.5 yards for the backing of each quilt and used buttons to secure the fabric together...
I found the buttons on the sweaters that I bought :)
Now for the edges....
You should make sure you leave about 3 inches of excess fabric around the edge.
Now you want to cut a line parallel to one edge of the fabric just up to the sweater quilt and fold in the corner.
Its a tough one to explain so hopefully the pictures help :)
