I found a pattern for these cute bunny cubes, here. I turned the cubes into boxes that could open and close. They would be cute to fill with Easter treats. There's also some chicks and other animals like the cubes above.
Some tips for making them:
Click here, for all the patterns. Click on the one you wish to print. Go to print preview. Scale them to 125%. Then print. To make them into boxes just add an extra tab to the top flap.
