Buy some balloons of different colors scattered in different corners or concentrated in the middle area, and tie the tail of the balloon with ribbons and vertical wires. It can be placed on the ground or floated on the ceiling.
Balloons are mainly placed in the sofa seat. Four or five balloons of the same color can be blown up, tied together to form a combination and placed above the seat.
At the entrance of the living room, balloons of different colors are arched to welcome. Then use other balloons to make different styles and fix them on walls, ceiling lamps, seats and so on.
Make a heart with a balloon in the blank position on the living room wall and hang it on the wall. Make a grape-shaped balloon and hang it in the middle of the ceiling lamp.
