/diy/ - Do It Yourself

Broke it a few months ago and managed to put it back together with glue and duct tape, but it's bottom right corner piece fell off and I lost it. How do I go about replacing it/filling up the space, so it looks like it's not missing? It doesn't need to be perfect by any means. I was thinking about buying clay, sculpting it to the right form, coloring it, and gluing it back at the frame, but don't know what glue I should use if it's clay. Please give me advice and other suggestions to fix the frame.
