An ornament stud for an article is provided. The stud includes: a head having a three-dimensional shape; a plurality of shoulders extending horizontally and inwardly from an edge of the head by a predetermined length; and a plurality of sharpened extensions extending respectively and vertically from inner edges of the plurality of shoulders, the plurality of sharpened extensions being spaced from each other along the inner edges of the plurality of shoulders by a predetermined distance.

The kit comprises a fastening structure and an anchoring structure. The fastening structure includes two vertical poles which are connected at their top ends by a horizontal bar and are inserted into two apertures of the button. The lower ends of the poles are attached to terminal elements. The anchoring structure comprises two trapping mechanisms which are configured to trap the terminal elements and to prevent them from detachment once they reach their trapping spots. The user places the fastening structure with the button above the cloth at the desired location and places the trapping mechanisms below the cloth opposite to the terminal elements. Next, the user pushes the poles downwards pierces the cloth and permanently traps the terminal elements by inserting them into the trapping mechanisms until they reach their trapping spots in which the resilient gates are released and occupy the cavities of the terminal elements.

A rivet is applied from a rear surface of a fabric for mounting a burr on a front surface of the fabric. The rivet comprises a disk-shaped base, and a shank projecting from and concentrically with the base. The base includes an annular recess around a proximal end of the shank, which is depressed in a direction opposite to the shank-projecting direction, and a flange radially outward from the recess. The flange includes a plurality of bumps which are raised from an upper surface in the shank-projecting direction. The bumps may be provided on the upper surface of the flange at equal circumferential intervals, and a top of each of the bumps may be a curved face. The recess may have an inclined outer surface adjacent to the flange. Each of the bumps may have an inclined inner surface extending continuously from the inclined outer surface of the recess.

Next, the user pushes the poles downwards pierces the cloth and permanently traps the terminal elements by fully inserting them into the trapping mechanisms. The user can create a buttoning gap by installing two spacing rings on the poles between the button and the cloth.
