I love Valentine’s crafts because they can be used all year long. Love is always in season.

Here’s a sweet and simple message in a bottle project for Valentine’s Day (or whenever), from Mini Eco.

The note inside is written in invisible ink (a.k.a. lemon juice), which your recipient reveals by holding the paper over a heat source. We were going to use this technique for our wedding invitations, but it didn’t work out, so now’s my chance!

Thanks, Jill from TerraSavvy, for the link!
