How do you make your own garbage bin, provided you already have a bag for it? I've tried using empty boxes, like the banana boxes produce departments give away. This never really worked well. Also there's something unappealing about having a bag full of garbage in the corner of the kitchen floor so I would prefer not to just use a bag.
Note, I don't care if the solution is to "make" a garbage bin or find a substitute tool for holding the bag and keeping it tidy.
