Step Five

Get out your sticky back velcro and first attach both sides together, then start cutting it into 1-2 inch pieces.  If you want an almost air-tight booth then buy 10 feet of sticky back velcro and you can attach it up and down each edge of the liner.  In my case, the smal strips work well because I am painting outside.  At each 6 inch PVC area where the liner overlaps, attach the velcro pieces about every foot or so. Start by peeling off the paper on one side and attaching it to the inside liner over the vertical PVC pipe. This will give you something to push on when you attach the liners together. I tried to be consistant and made sure I attached the "looped" side of the velcro on the inside liner. Attach your velcro pieces all the way down to the bottom, then one at a time, peel off the paper on the other side and attach the outside liner to it. Make sure to pull a bit on the outside liner to make it tight. Not too tight though, we want it to flex a little.  Complete all four sides with these steps.
