I've been trying to stuff trash bags in my shirt and blow them up since I can't find any stores here that sell large balloons, but I have a hard time keeping air in at the opening as I blow it up.
Anyone got any pointers on how to keep the air in or other alternatives? Thanks.
Let's start with what you're using to blow them up -- vacuum in reverse? Bike pump? Breath? I think that will help spur some specific ideas.
