To make a butterfly balloon, you need to prepare a long balloon first. Inflate the balloon to a suitable size and then leave a gap at both ends of the balloon. Next, starting from the middle of the balloon, twist the balloon into two equal circles, which will become the wings of the butterfly. Then, screw the two ends of the balloon into the head and tail of the butterfly respectively. Finally, according to personal preference, you can use the colors of decorations such as balloons to increase the beauty of butterflies.
