I made a quick, easy quilt for someone using flannel for the front and minkee back using the Missouri Star method of making self-binding receiving blankets

Instead of making it square I made it as wide as the width of the minkee would allow and used about two yards of the flannel (maybe less but it was rectangular, not square). That means the minkee was about 9 or 10 inches longer and wider than the flannel. It made a nice sized, but light and cozy cover. It all went together in a couple hours and my friend loved it.
It was for a man with bile duct cancer. I found a white flannel with sail boats because I thought he would rather be sailing than doing chemo. The minkee was white, also.
I think the suggestions about NOT using pink are spot on.
