Hot air balloon with a card in heart shape
For this self-made money gift you need a piece of carton and glue white clouds out of paper on it. Draw a heart and cut a trapezium out of red paper or just paint it yourself.
The bridal couple has to be drawn standing in the balloon and the bill is to be fixed in a slot next to the trapezium. You can frame the card to make it a special gift for the wedding.
