Editing Cufflink (section)

=== Closing mechanism ===
Cufflink designs vary widely, with the most traditional the "double-panel", consisting of a short post or (more often) chain connecting two circular disc-shaped parts, both decorated. Whale-back and toggle-back cufflinks have a flat decorated face for one side, while the other side shows only the swivel-bar and its post. The swivel bar is placed vertically (aligned with the post) to put the links on and off, then horizontally to hold them in place when worn. The decorated face on the most visible side is usually larger; a variety of designs can connect the smaller piece: It may be small enough to fit through the buttonhole as a button would; it may be separated and attached from the other side; or it may have a portion that swivels on the central post, aligning with the post while the link is threaded through the button-hole and swiveling into a position at right angles to the post when worn.

Links of knotted brightly colored silk enjoyed renewed popularity in the 1990s, joined by an elasticated section because they looked fashionable.
