Cardboard is a ubiquitous packaging material, especially if, like me, you order a lot of things from the internet. You could let those cardboard boxes, supports, and more stack up until you head to the recycling place...or you could put them to use, getting a few more rounds of creative use out of them before you finally send them off into that good night.
Sure, you might have cardboard boxes arrayed for storage under your cozy Philadelphia roof, but isn't that a bit...mundane?
1. Floor protection for events
Big cardboard boxes are perfect for this. If you're renting an event hall and you want to protect the kitchen and other flooring during setup, cooking, and service, put cardboard down. It will catch spills and stains, prevent scuffs, and add some shock absorbency for workers who might be on their feet for a while. It doesn't necessarily look pretty, but it doesn't need to go in the public areas where people would see it.
