I'm following up an earlier post when I said I would post photos of my garage when I had them. Here's one to show some of the features I used.
The walls are white with an 8" red stripe above a 4" gray stripe at the ceiling. The floor is mostly gray indoor/outdoor carpet with an island of MotorMat tiles where the cars are parked. The cabinets are from Sam's Club with a custom area for the TV. The trash can is a recycled 55 gallon plastic drum. This photo was taken at a Garage Reveal party I held yesterday.
