Here's a question for the crafty among us... (you know who you are

) I recently got a really nice Bagaboo messenger bag. It was meant to dethrone my (slightly modded) Booq from the EDC role and it is doing quite well thus far. I do have a few pet peeves with it, though, with the strap buckle attachment being the main one. These bags are built with a floating track tarp liner inside a cordura shell, which is good since it makes the bag virtually rainproof. The problem is that the female strap buckles are sewn on only the inner (tarp) part of the flap, and the sewing does not go all the way through the outer (cordura) layer. This is also a good thing, since it adds to the weatherproofness of the bag.

However, when the bag is loaded enough, the outer layer stretches to the back, exposing the inner layer up to the point where the buckles are sewn. That is, there is about 2-3 inches of the "yellow" part showing. I decided to take it to a pro to have the inner and outer layers of the flap sewn together near the buckle line. I also thought I could go the extra mile and add two "fluffy" velcro patches on the outer layer; that would allow me to show my mt.o patches to the world

and "hide" some of the sewing holes from picky rain drops in the process. Nice idea, huh? Well, it turned out the "pro" was not that much of a pro after all and he managed to mess up; he decided to cut the fluffy velcro patches as he deemed fit, and sewed them on at different angles on the two sides.

Needless to say, I had a nice little chat with the "craftsman", which of course didn't end well.

So, I spent some time last night (very) carefully removing the stitching and crooked patches and decided to do it myself by hand. However, before I embark on that endeavor, I'd like to somehow close the holes that the stitching left behind.
Here's where I'm asking for feedback. I have (tiny, but visible) holes on both the cordura and tarp layers, that I'd like to somehow close and/or waterproof. I'm considering adding some duct tape on the inside of the tarp and cordura, but I reckon that's a "hackish" way of dealing with this. Anyone has some better idea?
