My quilt guild makes pet pillows as a project and we donate them to our county animal shelter. They are made in various sizes and as we are doing a quilting project, all the COTTON scraps go into the pillow cover. We do not put any dryer lint or batting into the pillows. That way whoever gets the pet and the pillow can just wash it and throw it into the dryer without any worries of catching on fire. Also the dryer lint has a tendency to filter through the pillow cover causing dust which some pets are allergic to. So stay with the 100 percent Cotton scraps.
