Here is the final product. We feel that it is a big improvement as neither DW or I liked all the mirrors on the walls.
Before
After
When I stated that it took 3 days, I did not mean that we worked on this continuously for 3 days. We took lots of breaks for other activities. I did not keep track of the total number of hours, but I would estimate that it was about 15 hours total from start to finish, not counting the time spent cutting corks in half.
Next up.....
Replacing the mirrors in the kitchen backsplash with Smart Tiles.
