Choosing party decorations: buy balloon sets and confetti cannons to suit your celebration

Great-looking party decorations don’t have to be complicated. Unnecessary costs often come not from the price of individual items, but from buying the wrong thing: a balloon set contains fewer suitable items than expected, a balloon arch doesn’t fit the space available, or a confetti cannon isn’t allowed at your chosen venue.

Before you buy, it’s worth looking out for three common pitfalls:

• Unclear quantities: “Large set” doesn’t tell you much. The number of pieces, balloon sizes and included accessories are what matter.
• Unsuitable materials: Latex balloons, foil balloons and confetti react differently to air, helium, moisture and heat.
• Skipping safety checks: A party popper isn’t a toy. Check the age guidance, direction of use and instructions before setting it off.

What to look for in party decorations

1. Check the number of pieces and assembly accessories

For balloon decorations, the number of balloons should suit the space you have in mind. A small table needs far fewer decorations than a photo wall or balloon arch. It’s also important to check whether a set includes just balloons or fixing materials too.

According to the product description, the Unicorn Balloon Set contains 120 pieces. These include pink and blue latex balloons, foil star balloons, confetti balloons and a large unicorn foil balloon. Glue dots make it easier to assemble a balloon arch or backdrop. For family celebrations, note the stated age recommendation of 3 years and over. Keep balloons out of reach of young children unless supervised.

2. Choose air or helium to suit how you’ll use them

Latex balloons can generally be filled with air or helium. Helium creates a floating effect, but it adds to the cost, and how long balloons last depends on their size, material and surroundings. Air is usually enough for a fixed balloon arch. Before you buy, check whether you’ll need a balloon pump, string or ribbon.

With a unicorn balloon set, also check whether the large character balloon needs to be inflated separately and whether the colours will work with the room, table decorations or planned photo backdrop.

3. Choose confetti cannons to suit the venue

A confetti cannon, party popper or confetti shooter is usually triggered mechanically or by compressed air. According to the product information, the models featured here don’t need batteries or a fuse. However, you should still follow these important precautions:

• Never aim at people, faces, animals or delicate objects.
• Only use in areas that are spacious and clear.
• Keep confetti away from moisture, as the colours may run.
• Follow the age restriction and manufacturer’s instructions.
• Before use, check whether confetti is allowed indoors and how it should be cleaned up.

For a wedding confetti cannon, heart motifs are an obvious choice. For birthdays, smiley faces or mixed-colour designs may work better with your theme. Some metallic confetti can be reused as table decorations, but make sure you collect it all afterwards.

Practical checklist before you buy

• Measure the space: For a balloon arch, plan its height and width, along with where it will be attached.
• Choose a colour scheme: The style and colours of mixed sets may vary.
• Plan how to fill the balloons: Air is usually enough for fixed decorations; helium adds ongoing costs.
• Consider clean-up: Don’t use confetti in the rain or on damp surfaces.
• Read the safety instructions: Keep confetti cannons and party poppers out of reach of children and pets.
• Check the venue: House rules, your tenancy agreement or the venue may prohibit confetti.

Party decoration FAQs

How long do birthday balloons last?

How long they last depends on the material, filling, temperature and exposure to sunlight. Latex balloons filled with air can stay decorative at room temperature for the duration of a party. Helium balloons typically lose their lift sooner. It’s not possible to give a general estimate without knowing the size, material and storage conditions.

How do you assemble a balloon arch set?

First, inflate the balloons to suitable sizes and group them together. Then attach them to a strip or string, or use the glue dots provided. Secure the arch to sturdy fixing points, away from hot lights, sharp edges and delicate surfaces.

What are the running costs of a confetti cannon?

According to the product information, the models featured here are operated manually or by compressed air and don’t need batteries. So there are no ongoing energy costs. Remember to factor in the purchase price, possible cleaning costs and the fact that most confetti cannons are designed for single use.
