Choosing The Right Balloon Size And Material

- Foil balloons hold shape better and support larger, straighter number designs.
- Latex balloons offer deeper pigment saturation but may have a softer finish.
- Helium fill quality influences float longevity; treated helium lasts longer.
- Consider indoor only or indoor/outdoor rated balloons based on venue environment.
