DIY Large Beadboard Molding Mirror

After my stencil wall was completed, I knew I needed to beef up my mirror.  Solution for a bigger mirror?...a larger frame behind the original.  Best part: FREE!  
You might be surprised what supplies I used to create this big ol' chunky mirror:

Let's back it up real quick...my generous twinner, Kristi, gave me this cute, simple creamy mirror when I first moved into my new home 7 months ago [warning: cruddy cell phone pic]

Love the mirror, but it needed to be BIGGER on that big, busy wall.  I originally planned on 3 crown molding 5' shelves for the wall but after I stenciled it, I knew the knick knacks on the shelf would be too cluttery.

An after shot:

Here's what I did, and what you can do too!!

1. Start with a standard mirror, 1/8" MDF, bead-board wallpaper, trim [wallpaper+trim were leftover goods]

2. Cut MDF 8" larger than your mirror so it has a nice, chunky base.

3. Apply wallpaper to edges of MDF. This is nice because you can save your wallpaper and are virtually using scraps. Score.

4. Center + liquid nail original frame onto newly bead-boarded MDF.

5. Liquid nail trim. Secure with screws behind [optional].

6. Caulk, paint, glaze. [In the last picture you can see how thin the whole frame is from the side which is nice because it's lighter.]

Here it is next to my 7 year old son for comparison:

Side view and Accessorized:

My sis-in-law/neighbor walked in after I completed the room and said "I don't get the wreath?"  Haha!-do you agree or disagree??  I didn't put the mirror up to look at myself while I cook, I put it up for decor only.  What do you think?!

And one last shot:

Okay okay, I swear, the last one (:
