A button knot is a knot that forms a bulge of thread. Button knots are essentially stopper knots, but may be esthetically pleasing enough to be used as a button on clothes.

The single-strand button is a third type of knob knot, in which the working end leaves the knot at the neck, parallel with the standing part, so that the two parts, or ends, together form a stem. The lay of the two ends is the same, and the knot is symmetrical throughout.
