They migrate... frequently.
They multiply... often.
And they will randomly launch themselves at unsuspecting beverage seekers from their precarious positions in the kitchen cabinets!
If your plastic cups are taking up way too much real estate all over your kitchen (perhaps even invading the pantry!?!?), you might want to herd them up and give them a new home. Together. Where they will cause much less damage and frustration!
Although these cups aren't pretty (I mean, face it, we've collected these cheapies and freebies from decades of yard sales, birthday parties, concerts and ball games), they do deserve some attention. So summon your organizing prowess, and clear a cabinet just for the cups. Swallow your pride, and just stack 'em up by size.
Now, I've let some coffee mugs take up residence here, along with a few water bottles, but this cabinet is probably 83% plastic cups. Every once in a while, they'll start to form a rebellion and try to wobble and lean their way off the edge of the shelf in order to hit someone in the head or bounce all over the floor. But, most days, the cups stay pretty neat and organized. I haven't found a stray in the dog food for a while. And the cup count has remained pretty steady.
Now, THAT's neat!
