My wife and I found some grass clothe mirrors at a local home decor store that we loved, but they were either too big or small for our space. (Not to mention they ran $300-$450!!!) Using the same height/width ratio I built my own.
For this project we used:
-spare 1x4 and 1x6 pine boards left over from other projects (SORRY, I do not have the cut list)
-brad nail gun
-miter saw
-piece of 1/4" plywood (to hold the mirror in on the back)
-8 wood screws (to fix the plywood to the frame)
-an old bathroom mirror
-glass cutter (~$6-8 at Home Depot)
-gloves (for cutting and handling the glass)
-olive oil (for lubricating the glass cutter)
-grass clothe (had to buy it online by the roll ~$75, only used half)
-scissors
-spray adhesive (~$6-8 at Home Depot)
-picture hanger hooks (~$1 at Home Depot)
I spent more time thinking about how to construct the frame than actually making the cuts and building it, which took about an hour. I then spent about a month waiting for the grass clothe to arrive in the mail. Then it was about another hour cutting and affixing it to the frame with my wife.
