From all the times I have sealed the edges of a seam, I've never heard anyone on how to solve this problem, not even CFI OR CRI. Can anyone here enlighten us? Take any piece of carpet and seal the edges of that carpet. Then seam that carpet together and just watch as the glue on the sealed edges is reaheated by the iron and the edges drag on the neck of the iron and pull at least some of the fibers a little further down below the nap surface. I have seen it do this time and again, so I was wondering how our industry solved this little problem. Of course many say our seams are supposed to show, like the seams in our clothes. hahahahaha, I just saw the word irregular under my moniker. hehe, ok, who's playin with the nobs.
