I enjoy making quick simple projects. Previously I made my favorite k-9 boys matching bandanas from 100% cotton material that was blue with small white paw prints on it. This time I decided to use some black and white checked 100% cotton flannel material. For our big boy, KC, I cut a 20″ square and for our little guy, Rico, I cut a 14″ square. I did not cut these squares into two bandanas, but instead I folded them in half diagonally and made them reversible. I add velcro to the ends. A perfect fit and easy to put on and take off.
