No need to mark on your door jam anymore! Our growth charts are printed on canvas, using a giclee machine. We attach a wooden dowel rod at the bottom, to give the growth chart weight, and one at the top with twine for hanging. Each growth chart has a clear sealant. We recommend using a permanent marker when marking your child's height. They can be personalized by adding the child's name. These make excelent gifts as well!
