I always use an empty tissue box to store all of those plastic bags from the grocery store. I keep one under the sink in the kitchen, and one near the cat's litter box. I just pull them out as needed. It's an extremely convenient way to conquer the plastic bag jumble, and an easy access way to re-use them.
My girlfriend always keeps one in her car. She uses it as a trash can. All of the bits of wrapper and straw paper pushes nicely through the plastic hole at the top, but won't come out easily. Once the trash receptacle is full, it can be disposed of. It's an ingenious way to re-use and re-purpose.
And, now for the surprise:
Did you know that you can design your own Tissue Box? The Beautiful people over at Kleenex let you Design your own. How fun! Now, you have a new gift idea for the person on your list that has everything! (for a mere $4.99).
