- (a) an outer shell having a front wall with an image forming surface thereon and a generally transversely extending sidewall portion defining an inwardly facing peripheral groove, one side of said groove being spaced from said front wall, said groove having a diameter defined by a distance across said shell at the bottom of said inwardly facing groove;
- (b) an elongated resilient removable inner cross member having a longitudinal dimension greater than said diameter and opposed contact edges shaped to substantially conform to said groove;
- (c) said cross member being connected to opposing sides of said shell with said contact edges engaging the surface of said groove, whereby said cross member may initially assume an outwardly bowed position when a layer of fabric is placed between said cross member and said shell, and be forced to an inwardly bowed fastening position through an over-center action.
- 2. The structure of claim 1 wherein said shell and cross member are constructed of like material, the material being a plastic sheet having a thickness in the range of 0.010 to 0.040 inches.
- 3. The structure of claim 1 wherein said inwardly facing groove is annular in shape and said contact edges are arcuate segments of substantially the same radius of curvature as said groove surface.
- 4. The structure of claim 2 wherein said cross member has a pair of arcuate inwardly concave longitudinal edges, said outer shell sidewall portion is substantially circular in form, and said longitudinal edges and sidewall portion have substantially the same radius of curvature.
