Next you should pinch 2 of the points on the card horizontal to each other. Then twist them clockwise. This SHOULD collapse the whole card into a hexagon shape but it may take some help to get the other points to fold correctly. Work the card a few times until it folds easily.
Now you can open the card and attach all the embellishments. Look at the picture above if you need to know where everything goes. As I said earlier the shamrocks on the center hexagon come from the leftovers from the rest of the embellishments.
Since the shamrocks were cut from 2 sided patterned paper I alternated the two designs around the card.
