This awesome craft idea is not my own, so kudos go to Our Best Bites for the idea. They called theirs dinosaur eggs, but we went with dragon eggs instead because they look so mystical. This might be kind of a fun project to do after reading The Paperbag Princess with your little one.

When your eggs are cool enough to work with, gently crack the shells. It's a good idea to do some bigger cracks and some smaller ones just to make your final dragon eggs look even cooler.

Allow your dragon eggs to soak in the dye. We only did ours for an hour or so, but it would be even better if you put them in the fridge to soak overnight.*
*We made our dragon eggs a second time and made the dye much darker and let the eggs soak for about 3 hours. The colors came out so much more brilliant!
What I Learned the Hard Way:
Like I mentioned above, I would soak the eggs much longer next time to make the lines appear darker once the shells were removed.
Great trick with the eggs. I might try it with my kids this year.
