Two Trees is the brand of a talented Belgium artist who makes handmade things and also interior design. She has a beautiful tradition - for every 10 projects or items that she manage to sell she plants two trees. Her art is inspired by nature so is the Two Trees logo. The lines flowing into each other represent the magic of working with glass, clay, silver, porcelain, etc. Here you can see some of the phases of making the logo.
