"He who marches out of step hears another drum." ~ Ken Kesey
we use a box, fold the flaps out, when done fold them on top and tape it up. we use boxes as garbage cans a lot around here, they fit under presses and save a few steps when you need to throw stuff away. and you're not buying bags that you will only throw out in a few days.
We don't use tape.. at all.. permanent blockout is so they way to go.
