This is a generic pattern for mirrors that are somewhat rectangular in shape. Mirrors don’t have to be perfect rectangles as there is give in the finished product. A basic rectangle is made for the back of the mirror, then the sides/top/bottom are made, kind of like a basket. The cozy is made to be easily attached or removed by the use of a button. Pattern includes the directions for a dog paw decoration though anything can be used to decorate the cozy.
