ABSTRACT:
An art work stretcher assembly is disclosed having any desired arcuate, e.g., elliptical, shape. The stretcher assembly includes a plurality of plastic tubes that are flexed and arranged with their ends in abutment so as to provide a closed loop. A separate wooden dowel is inserted into each pair of abutting tube ends, to hold the tube ends together and to provide increased rigidity, and thus reduced curvature, in those regions of the closed loop. An elongated wooden strip is secured to the inwardly facing side of the closed loop of tubes, to provide a surface onto which can be fastened a planar art work substrate such as canvas.
