Abstract
Abstract A button fastener for attaching an item, for instance a button to sheet material and particularly to fabric, by placing the button on one side of the fabric and by looping a flexible filament secured on one end to an elongate sleeve successively through the fabric, the holes of the button and again through the fabric. The filament is then threaded through the sleeve and pulled as tight as desired. The sleeve wall locks the filament portion now located within the sleeve in its tightened position, thereby securing the button flatly to the fabric with the sleeve anchored flatly against the opposite side of the fabric.
