Still got cardboard boxes hanging around after the holidays? Put them to good use! Cardboard is a surprisingly sturdy material that's also easy to cut, fold and otherwise manipulate. The only downsides are that water will destroy it and it burns quickly.
You can cut it with sturdy scissors or a sharp knife, paint it, decorate it with contact paper or colored tape or decoupage it. As a matter of fact, it will do a lot of things that wood will, and it's a lot cheaper (free!).
I just came across a really cool shoe rack you can make of cardboard here, but that's just the tip of the iceberg. You can make anything from emergency tables for kids to "paper" chains that will last holiday after holiday.
One of the easiest things to make from small cardboard boxes is storage boxes and bins. Sure, you can use them just like they are, but what's the fun in that? Go dig up some leftover paint and/or a leftover strip of contact paper, or yesterday's newspaper and decoupage glue. Have fun decorating a few boxes that you can leave out in plain sight instead of shoving them to the back corner of the closet. You can make them a lot prettier than any storage box you can buy and you can customize them to exactly suit your room!
Never get rid of a cardboard box without asking yourself if it will fill a need in your home. There are lots and lots of pages on the internet with so many projects made from cardboard that I couldn't even list them here.
Let us know what you find and what you decide to make!
