I promised quite a while ago that I would give directions on how to frame a builder grade mirror that is not tight between 2 walls (like my first post here).
My daughter's bathroom has a mirror on a long wall and we needed to find a way to conceal the mirror when looking at it from the side (since the frame sits on top of the mirror).
We used the generally the same materials and mostly the same method to create this frame. For detailed instructions on how we made this mirror frame, please refer to this original post.
I am only going to show you how this frame differs from the original post.
This frame was much more difficult for my husband to create. We could not just create a frame with straight cuts and not have to worry about how the molding was finished on the sides. Since the frame is adhered to the mirror, we had to determine a way to hide the mirror when looking at it from the side and we also had to finish the crown molding and flat trims (making it into a 90 degree corner) so that it was finish nicely.
Once the frame was secured, we used some filler (like DAP or caulking) to fill in the seams between all the pieces used to create the frame. This gave the frame a nice finished look. It made the frame look like 1 piece and not a bunch of little pieces stuck together.
Please let me know if you have any questions. Enjoy!
