I used a sheet of half inch plywood, used narrow wooden trim for the frames, used eight in sq candle mirrors from walmart, I first dry placed all the mirrors and wood pieces then used liquid nails to make sure they stayed. Its not perfect but it did the trick for what I wanted and I saved seven hundred dollars.. ( pottery barns Eames Mirror is what I was trying to replicate) Hint be sure to stain the plywood before placing the mirrors etc permanently.
Stain • Candle mirrors • Half in plywood • Wooden trim • Liguid nails
