It's not comfortable walking into a closet and being assaulted by a million broomsticks bruising your shins and tripping you when all you're trying to do is extract the laundry detergent from the corner.
Instead of fearing for your life every time you enter the broom closet, grab an old pool noodle from last summer and glue it to the wall. Cut some slits into it and you've got yourself a broom holder.
