I decided to retire the sock after purchasing and trying out a SmudgeGuard™. What a difference! Not only can my hand breathe, but it doesn’t leave that unsightly elastic mark on my arm. This product that Jeannie Lit has created is fantastic! It allows my hand to glide across the Wacom tablet without skipping, sticking or bumping, which helps with a smooth line. If you are experiencing this problem with your Wacom or if you are sketching in pencil or charcoal on paper, head over to SmudgeGuard™ today and buy one of these puppies. No, they are not made from actual puppies and I am in no way connected to Jeannie and her product other than being a very satisfied customer.
