I used a wool jersey that I purchased at our church harvest fair for $1.00 for the backing. Let me tell you, this is the coziest blanket we have ever had. The best part is that it is the one everyone "calls". Even me. I just don't get it until the kids go to bed. And then my husband knows, that I call the sweater blanket. Maybe tonight I will let him have it. Maybe.
Have a wonderful weekend!
