Dan, thanks for the info, it is helping! Aside from binding, what other methods are there to prevent unraveling? Specifically when I have the tunnel carpet glued in place, I will need to "butt" the edge of the floor sections up to it. This is why I have sewn this in the past. It takes forever to sew it all up AND get good fitment. The backing of the carpet doesn't hold up well to that.
A little more info about the current project, it is a '78 Datsun truck. I know this should be really simple. I want this to turn out well, so I am asking for some assistance.
The floor was covered with sound deadening (eDead) and then I put down a layer of padding. This is where I am now. A few photos.
