Every kid loves to play in an empty cardboard box. So why not create a whole entire theme for a party based around cardboard boxes? The ladies at Hello Lucky did just that and with their usual wonderful designer flair! Sabrina's twin boys were celebrating their first birthday! Thank you ladies for sharing this wonderful party with the rest of the world! The invitations were printed on kraft board with box-inspired envelopes. The party was billed as B.Y.O.B. (Bring Your Own Box)!
