Hanging, whether partial or full suspension, will leave dark red bruises around your neck. The bruises won't be as bad with a partial suspension, as you won't have your full weight pulling down on your neck. They will still be bad, and quite visible. They will clear up a little quicker than if you hang yourself fully suspended. With full suspension, your weight pulling down on your neck will cause the rope to dig into your neck and cause rupturing of blood vessels that are under the skin. With a full-suspension hanging, it could take several weeks for the marks to clear up. The last time I attempted to hang myself (April 19th), my neck had bruises so deep, it took almost two months before they cleared up.
