Repurposing milk cartons

Of course, you can take two milk cartons (the waxy cardboard things) and cut off the tops and fit them together to make toddler building blocks.
When you've had enough of that, try making each box into a little storage box. I've been doing that lately, and I'm excited about the growing collection. I haven't decided whether to keep the repurposed-chic look, or decoupage them into a less-busy looking collection.
