I'm gonna stop by the container store within the next few days to buy some sling containers and I was wondering what people think about ventilation methods. I know some people like to cut a hole in the container and place a screen over it, while others simply drill holes in the container. Is there a right way to do this? As in, is one method better than the other? I think the screen vents look nice, but I've just been using a drill to drill holes in my containers, mostly because I don't have a hole saw (or know how to use one) and I don't know where to (and what kind of) screen to buy. Thoughts?
