My brother-in-law is a huge BYU football fan. So for Christmas I went in search of his team's fleece to make him and his 18-month-old son matching blankets. While I didn't find the right team fleece I did find this fabulous minky football fabric that is even better. I lined the back side with fleece for thickness and made my own logo on the front out of the same.
This blanket was for my nephew. It's about four feet, square.
Here's the blanket for my brother-in-law. It's about 6 feet long, maybe longer.
I only had to cut the "Y" out once. I used the reverse for the baby's blanket.
He looks pretty happy about the gift, don't you think?
