Abstract
A peripheral frame member holds flexible sheets of material tightly over a central open area. A channel around the back of the frame is adapted to receive a flexible strip member having a longitudinally extending bifurcated projection engageable within the length of the channel. When a thin sheet of flexible material is placed over the back of the frame and the strip member pressed down so that the projection fits tightly within the channel, the material is locked in place and stretched taut across the central open area. The frame is preferably rectangular with channels along each side and a plurality of longitudinal strips engage respective sides. The device provides a simplified structure which is particularly useful for holding and displaying fabrics for embroidery and needlecraft projects.
