It's a little early to decorate now, usually two or three days in advance. Have you hired a wedding company? We are a wedding company, and the arrangement of the couple's wedding room is included in the wedding package. We are all arranged directly by professionals at home, so the couple don't have to worry about themselves. If you don't invite, the simplest thing is to hang flowers and paste them directly with wide transparent glue. Balloons are troublesome, but you can hang some in the four corners of the room. You can also spell a balloon shape around the wedding photo. But remember that the happy words and couplets on the outside door should be posted later to avoid damage.
