I just got my Speedy 30 a week ago, and I noticed that on one of the darker "squares" there appears to be a slight waxy or gluey looking thread on it....looks like it almost could be excess coating or something? It's very small, but of course I know its there........so it jumps out at me. What do they coat the canvas with, and has anyone ever noticed that on one of the damier bags? I don't want to pick at it or anything, I was just gonna leave it alone, but I wanted to make sure it was nothing major. It's really tiny, so I feel nuts for even asking.......but well, you know how it is. Any thoughts?
