For gripping and stretching fabric such as art canvas, a system of specially-shaped gripping members are attached to the material in line along each edge in a manner that in co-operative engagement with the frame via special frame channels, facilitates two-dimensional stretching and mounting as well as subsequent dismounting of the material from the frame, rolling up for shipping or storage, and reassembly and re-mounting onto the frame. The gripping members slide into the frame channels which then engage a fixed or adjustable frame; optionally the fabric may be stretched around the frame perimeter. The gripping members are attached in pairs: one on each sides of the fabric, arranged in line near the edge of the fabric and are made to slide freely in the frame channels to enable two-dimensional stretching of the fabric. The members of each pair are permanently attached together by wire staples or thread, gripping the fabric between interfacing surfaces which may be shaped to enhance gripping. Optimal spacing between pairs provides good gripping and yet allows the fabric to be removed from the frame channels and rolled up for transportation and shipping purposes, and subsequently easily re-stretched onto the frame. The gripping members may be molded in multiples joined together by curved flexible strips that accommodate two-dimensional fabric stretching and automatically set the optimal spacing.
