DS is having a small party at a trampoline park this weekend. I bought a pack of balloons from Amazon and they're all foil, and can be air filled or helium filled. I'm just debating how to decorate with them if I just filled them with air, since they won't float, and also since it won't be a venue that I can freely decorate, we'll just have a table set aside for us. Could I buy those plastic balloon sticks and stick them to the backs of chairs? Would that even work? If I tie them with ribbon will they just sag down to the floor? Do I just to go and spend another £25 on a helium tank? Can't decide on the best plan of action...
