Hi, I designed this big size card as a wedding gift for a couple. The theme is the story of the couple from the day they met, Inside there are 2 folds, one will open on left side (3ft long), and the other on right hand side (3ft. long). So from inside, this card is 6 ft. long. And each side has small handmade cards, wedding messages, photos, and other designer stuff. And then inside there is a big heart, half on each side, so when you join the full card, its a full heart having their picture, (one on each heart).. A typical task to explain..... Will add some more photos soon...
