My project: Build a large frame around large mirror and use as coat rack. Supplies that I have: 3/4" x 4" boards. 1 large old heavy mirror. Heavy duty metal coat hooks. Paint. Process: I will have the big mirror cut to size; approx. 4 x 2. My question re: the process. Could I get holes drilled into my mirror when it is being cut to size. Then secure the mirror to the plaster wall using screws and heavy duty plastic anchors. Then build the frame (mitering the corners)and secure frame to the wall butting the wood up to the sides of mirror & securing to wall. And finally securing the heavy coat hooks to the wood frame only or take the nails/screws deeper into an anchor in the plaster?
