I have made several comfort covers recently. I have used no-pill flannel. One was football themed for a guy using his favorite football team's logo. The second was for my SIL and the front was pics of puppies (she is a dog lover), flowers, etc. The back of her's was a very hot pink. Her's was 60"x72". Both of these were clipped around the edges and tied. MSQC has a tutorial on how to do this. Very quick and easy.
Both of these were used during their treatment times, at home afterward treatment, and was large enough that a grandchild could cuddle with them under the throw. They said they like the warm fuzzy feel of it being flannel and happy prints.
I do wish I had put ties on one end so it could have been rolled and tied as sleeping bags are sometimes and I wish I had made a small travel pillow and case to go with the throw.
Rest assured that your quilt will be appreciated and loved.
