"Propping up rolls of gift wrap in the corner of a hall closet often means wrinkled, torn or lost rolls. Here's a way to keep the rolls neatly organized and easy to reach.
Make a wrapping paper "corral" by screwing a small section of wire closet shelving vertically to the side of a closet wall. Just slide the rolls in!"
