Wrap your gift with a Furoshiki
This method straight from Japan is spreading more and more in the western world. Furoshiki is a square shaped fabric but also a traditional wrapping and knotting technique that will allow you to drape any object and carry it everywhere. Your Pierre Lannier box being rectangular, it will be very easy to fold the corners facing each other and make a nice knot with the other ends. Arrange the whole to smooth the folds, and you're good to go! It is possible to make your own Furoshiki from old sheets, scarves or clothes, the trick is to get a fabric opaque enough to hide your gift and not too stiff to wrap it easily. Then embellish your fabric wrapping with a few plant decorations (cotton flowers, holly branches, fir branches, etc.) and your gift is ready!
