I don't disagree--good advice in general if you want to find out if your weld is "good". See my exchange with Spider a page up, I'm walking the line between enough penetration and burn-through. Thin material is tough.
For thin stuff like dry boxes, most of what you see is what you get. Porosity (leakage, not to mention weakness) would be a much bigger problem than incomplete penetration--either will be obvious if your box leaks. With this thin of material, "pretty" is most likely also strong.
If you manage to get a small puddle on the backside and don't have burn-through, you know you have complete penetration!
If this was 1/2" base material, one could easily have a pretty weld that was invisibly weak with poor penetration. Just my $0.02.

Gotta love good feedback.

In a couple weeks I could work on what you'd like and send it to you for nada with hopefully some frame welding considerations for later.
I have a decent supply of corduras, some nylon fabric and some mesh.
I'll offer sewing/customization in MT.
