Note for sizing: Need to know what size stockinette to order. Simply measure the circumference of your leg or arm. Stockinette is measured in width so basically it is the diameter value. So you would double the value. As an example 3" stockinette has a circumference of 6", 4" stockinette has a circumference of 8". Stockinette will stretch some, so you have about 0.5 to 1 inch of stretch to that circumference value.
