Usually the wedding you are looking for will tell you this. I don't know if you want to do it yourself
In fact, the dolls are all just bought, and they are all used to make a doll. I wonder if you have noticed this. They are all plush. If it's a gift for guests, we need to buy more. Not expensive either. Buy some festive colors, such as gold powder and red.
So is the balloon, depending on how it is used. You must buy a lot if you want to fly to the end. At least, if you want to fly 200 balloons, you have to buy 300 balloons. If you decorate a room or scene with balloons, just buy one hundred or two hundred balloons. Not much. Remember to buy an air pump. Otherwise, no one can blow this.
I hope these suggestions are helpful to you.
I wish you a happy wedding,
