What kind of air cushion is it? Blowing is ok, but I'm afraid the air cushion can't reach the satisfactory internal pressure, because the air pressure of the hair dryer is generally not high. The wedding company's hair dryer specializing in blowing arches has a slightly better effect.

If the air cushion is not elastic, it can be filled with a hair dryer. If it is flexible, it is not recommended to use a hair dryer.
