When I visit Brazil one of the things I have to bring back with me is coconut soap. There, it's typically used for hand-washing clothes but I like to use it as a deep cleanser for the face (and skin overall) and it's perfect for the soaking portion of your pedicure at home. The coconut oil acts as a light moisturizer as it cleans, leaving everything soft to the touch.
They come in big chunks (depending on the brand) and are super easy to cut into smaller pieces, especially if you don't want to use the entire bar at once.
Using some hand-printed canvas material (heavy enough to not get oil spots from the soap) I wrapped each bar, tied it with yarn, and added a little lavender as an accent. The result is a little souvenir from Brazil to give to friends.
What kinds of gifts do you bring back for friends when you travel?
