I made a bunch for our local shelter, I got flannel on sale at Joann's to make really large ones because they said a lot of the big dogs dont get many. They asked to keep them not too fat, so i did flannel, batting and either more flannel or fleece. I also quilted them fairly heavy because they get a lot of wear and tear in the washing machines. And I sealed each one with lots of love and a prayer they find a safe and loving home.
