Top Secret Love Notes

This is one of the coolest valentine ideas I’ve seen on the web yet. Write your loved ones a secret message in invisible ink. All you need is some lemon juice and a heat source. For the full how to, head on over to MiniEco. This blog is one of my favorite stops on the Internet - colorful photography and a plethora of crafts that are easily accomplished at home.

Wouldn’t this be a fun activity to encourage a budding writer or artist? I’m planning to give my daughter a message full of hearts to show my love.

Shhhh! don’t tell her, it’s a secret!


  1. I love the beautiful photo and hearts. We did a similar experiment but instead of heat source used iodine solution

  2. Oh, this gets me thinking of making a secret message using white crayons.

    Thanks for sharing this.

  3. LOVE LOVE LOVE IT! I'm totally stealing this idea. Thanks for posting about it!
