I am not into Extreme Couponing or anything to necessitate an entire wing of my home for extra items. My hubby just likes me to have stuff "at the ready" anytime so we can have company over anytime! My kitchen pantry can't hold everything so between this and my basement freezer, we can have extra stuff here to feed anyone at any time!
I have lots of table cloths that I bought pretty cheap - both cloth and vinyl - to use for throwing a quick tablescape and if they get dirty I'm okay with it! They are long and rectangular so I can make them fit just about any table size.
I keep the regular overstock of foods and cleaners and paper goods down there, too. One thing that I keep is lots and lots of extra "disposable" containers. We have many needs in our church body for meals. So, I bring a meal to one family a month {this is my limit, but I love to do it}. So, I always bring the meal in disposable containers - butter tubs, restaurant take-out containers, jars - so that they don't have to wash OR return any dishes to me! I wash and stack them down here to use. How do you store overflow stuff?
