Here is one of 4 orders I had for personalised A4 wedding cards. They were a bit of a nightmare as so hard to fill such a huge card.
I used a Kanban topper with some white swirls (Doohickey I think) then the Martha Stewart deep edge punch along the side, some ribbon and a chain and heart from ebay. Think it works OK but still not 100% happy with it. Think it is the size thing.
