Urgent! I want to tie an arched door with colored balloons on National Day. How to tie the two colors? Ask an understanding friend for help and tell me the specific method.

Tie the two colors separately. There are many patterns, but you can't use colors evenly. That's boring. You should have a main color, such as: red is the main color, 5 red 1 yellow is tied into a ball, and then tied into an arch. Or tie 5 yellow 1 red into a ball, then tie it into an arch, and make the extra arches on both sides.
