I have one for a mini trash can and a place to hang my scissors. Best thing - I'm never losing my scissors in a mess on my desk.
I have one on the inside of each door of this little cabinet - holds my Martha Stewart large circle cutter and my ring of embossing folder samples.
I also have one on the wall at the side of my desk which hold my cricut mats. And another one next to my sewing desk that holds my self-healing rotary cutting mats and ruler.
