We got a new machine! But getting it tuned to crank things out properly took a few tries and now we have some seconds. The main issue is the binding tape on top. If it doesn't come out nice, it goes into the seconds pile. So most of these have imperfections in the finish binding around the top. Other imperfections may be a bad grommet placement in the bottom or just a wonkily sewn bag that isn't round enough for our standards.
