Heart shaped card with hot-air balloon
This idea with a rolled up bill in a basket of a hot-air balloon is really unique. You need a piece of blue carton for the background and some white paper to cut out the clouds. That would be everything you need to make the sky. Then you take some red paper and cut out the heart and a trapezium for the basket. The trapezium is not to be glued together at the upper right part as there the bill should be placed. The wedding couple can be painted or tinkered and glued into the basket.
