agree the sewing of the string was very loose ...............I did mine with the mesh down and the strings up. Take your time keeping the strings worked under the foot on the machine.
I too agree that the stitching could be a whole lot better. Without upgrades/repairs this thing sheds a lot. Even if the same stitches/inch were used but double stitched it would have been a lot better. This suit sheds at least twice as easily as the other ghillie I bought from APC.
I repaired mine the same way, i.e., strings up and mesh down. Same comment about the strings catching. I have not done the arms because that's a pain.
It is best to do this work right when it comes out of the box. Otherwise I would guess it would be far more difficult.
The thread I am using is heavy duty, but so is my fabric welder. It will go through a few layers of cordura nylon (and often does when I'm customizing other stuff).
The head sock is tight fitting, but cutting out the mesh and wearing a baseball cap works well. However, then I can't wear my electronic earmuffs, so that doesn't work well. If you weren't going to wear muffs I'd say I like the design very well -- except in hot weather because there's no way for air to move past your head.
I haven't had mine out yet because it seems hotter than my old one. Come fall it will see the fields.
