Cotton, washable.
Kennel covers are hand sewn by my Amish friend. I made a design that I thought would work great in all spaces. All sides roll up and tie. Corners snap. These are great in giving your dog his own space. A space that can make him warmer in the winter and keep him out of the sun in the day. They are also great in keeping loose hair contained and off the walls around a cage that isn't covered.
