Altered milk cartons!!

Here's a fun idea for you that uses a common household item: altered milk cartons! It might sound kind of wacky, but once you start looking at all of the fun things you can craft from these versatile containers you'll be hooked on altering them.
There are a variety of sizes and shapes available at your local market. I've used half-gallon cartons and the small 8-ounce-sized container as well. Tall, skinny quart-sized containers are easily found, and could be used to make a smaller version of any of these projects.
The very first thing you want to do, other than use up the contents of the carton of course, is to thoroughly wash out the inside and outside of your carton with hot water and dish soap. Be sure to allow enough time for your cartons to totally dry.
Once you remove the top from your carton you essentially have a square, open-topped container. From here it's just a matter of using your imagination. These containers are water-tight so you can craft adorable little window box herb containers, desk organizers for small items, candy containers, small themed serving bowls, wine box, candle holders, and any number of other small projects.
Wouldn't this be adorable altered and filled with birdseed? Put one nestled on a window's ledge and you could watch the little birds enjoy their treats. Or how about covering one in paper that matches your bath and filling it with small decorative soaps to put beside your sink in a powder room? As long as you protect the outside with a few layers of sealer your container should hold up quite well.
