A frame assembly capable of self-stretching fabric evenly has an outer frame, a demountable inner frame mounted in the outer frame and a positioning mechanism with retaining flaps and engaging sections disposed between the inner frame and the outer frame. A patterned fabric covers a front of the inner frame and is wrapped on an outer annular surface of the inner frame. The inner frame is then pushed into the outer frame, so the fabric is held between the outer frame and the inner frame, and is stretched and evenly smoothed by the positioning mechanism of the frame assembly. When the inner frame is pushed out of outer frame, the fabric can be changed and replaced with another fabric with a different pattern. Therefore, replacing the fabrics on the frame assembly is easy and the fabrics are not damaged. |
