Well I first picked out my material. I didn't want to use carpet so I chose fleece. its super soft to the touch and looks clean. I bought 3 yards of it. $15.00
Then I bought sun spray on adhesive. It's meant for fabric, and will bond to wood, metal, plastic, other fabrics, foam, rubber and what ever else you can think of.
then it is just a matter of laying it out and cutiing it to fit what ever you are covering. I folded everything over first to see how it looked and how it would go together before I actually sprayed on the adhesive. I also used staples on the bottom side to help attach the fabric.
pretty easy man.
oh yeah. I just found out my sub arrived. So I'm taking the after noon off from work to go home and install it. I'll have some pics up later today!
