A method of suturing a wound using a length-control technique. The method includes the step of placing a first pass of suture having barbs, with a first pre-attached needle, completely through the skin of the wound, from the undersurface to the outside, at a shallow angle just beyond one apex of the wound. The method also includes the step of placing the opposite end of the suture, with a second pre-attached needle, completely through the skin of the wound, from the undersurface to the outside, at a shallow angle just beyond the opposite apex of the wound. When the skin is pushed down on the suture, the suture pulls both apices towards the center of the wound to connect both apices to each other.
