I purchased 2.25 yd of fabric at $12/yd, originally $19.99/yd. I wanted to add some color to my room, but totally forgot when purchasing the fabric. When I got back to my office, I realized that I had bought the same tan-beige color that EVERYTHING in our apartment seems to be. Old habits die hard. I'll have to get some colorful throw pillows. I ended up only using about a yard of the fabric so I saved the rest to do another upholstering project that I had in mind.
I also purchased a staple gun for $19.99 at Home Depot, two foam pads for $6.00 (more about that later) and a pre-cut piece of MDF for $4.39. I also got some brackets to attach the board to the speakers. With a $5.99 can of spray paint and a hot glue gun in my hand, I was ready.
