Double-stuffing a balloon means putting one latex balloon inside another before you inflate them together. The inner balloon sets the colour, the outer balloon softens or shifts it, and the result is a tone you can't buy as a single balloon — dusty pinks, muted sage, tan, grey-blue. It's how most of the "custom" colours in organic garlands are made. Below: how to do it, what each pairing gives you, and when it's quicker to buy our pre-stuffed pastels instead.
What is a double stuffed balloon?
Two balloons of the same size, one inside the other, inflated as one. You usually see it done with a coloured balloon inside a White or Pearl White outer — the white layer knocks the colour back and gives that soft, hazy finish that nursery, baby-shower and wedding palettes lean on. But any two colours work: a dark inner with a light outer mutes the colour; a coloured outer with a different coloured inner creates a new shade altogether.
At Stylex we sell pre-stuffed pastel mixed bags (already paired, ready to inflate) and every single colour in every size so you can stuff your own combinations.
How do you double stuff a balloon?
- Pick two balloons of the same size. A 12" inside a 12", a 5" inside a 5". Mixed sizes don't inflate evenly.
- Stretch the outer balloon's neck and push the inner balloon in, neck first, until only the inner neck is poking out of the outer neck. A balloon-stuffing tool (a short tube) makes this fast; by hand works fine for a few.
- Line up the two necks and inflate both together through the inner neck. The inner balloon fills and pushes the outer out with it.
- Inflate slightly under size — about 10–11" on a 12" pair. Two skins are stiffer than one, so pushing to full size strains the latex.
- Tie both necks together in one knot.
For a 3-metre garland that's 30-plus pairs, which is the main reason the pre-stuffed mixed bags exist.
What colour do you get? A double-stuffing chart
These are pairings I use on real jobs, all from the Stylex range. "Inner" is the balloon that goes inside; "outer" is the one you see. Results shift slightly with inflation size — larger reads lighter.
| Inner | Outer | What you get | Use it for |
|---|---|---|---|
| Rose Pink | White | Soft powder pink | Baby showers, first birthdays |
| Berry | Blush | Dusty raspberry | Bridal, Valentine's |
| Hunter Green | White | Muted sage-grey | Botanical, eucalyptus themes |
| Coffee | White Sand | Warm tan | Boho, safari |
| Burnt Orange | Coffee | Terracotta | Autumn weddings |
| Golden Rod Yellow | Coffee | Deep mustard | Autumn, boho |
| Navy | Pearl White | Dusty slate blue | Modern, gender-neutral |
| Lavender | White | Pale lilac | Spring, unicorn themes |
| Red | White | Coral-pink | Summer, tropical |
| Black | White | Mid grey | Monochrome, corporate |
| Caribbean Blue | Hunter Green | Deep teal | Peacock, jewel palettes |
| Baby Blue | White | Ice blue | Winter, christenings |
Rule of thumb: a white outer lightens and softens; a coloured outer tints. If you want a colour muted but not lighter, put the lighter colour inside and the darker one outside — the effect is subtler.
Single pastel or double stuffed — which should I use?
We stock both, and they do different jobs.
- Single-colour pastels (Pastel Pink, Pastel Blue, Pastel Lilac, Pastel Green, Pastel Yellow) are pigmented to a soft tone in one skin. Use them when you want a clean pastel that stays consistent across a big install, or for anything on helium.
- Double stuffed gives the muted, hazy look and lets you hit a colour that doesn't exist as a single. Use it when the brief says "dusty", "muted" or "custom", and for air-filled garlands.
Our pastel balloons page lists both.
Do double stuffed balloons float?
Yes, but two skins are heavier than one, so float time is shorter than a single balloon of the same size — plan on less than the usual 12–18 hours and treat them with a float product if the install needs to last. For helium work, singles are the safer choice; for mounted garlands and arches it makes no difference.
Does double stuffing change the finish?
A little. The outer skin stretches over the inner, so the colour reads slightly softer and the surface slightly less glossy than a single balloon. Chromes don't double-stuff well for that reason — the mirror finish is the point, and an outer skin dulls it. Keep chromes as single accents in a double-stuffed garland.
Where to start
If you've never double-stuffed, buy a Sample Bag (one 12" of every colour), a pack of White 12" and a pack of Pearl White 12", and spend an hour pairing. Photograph each result next to its label — you'll end up with your own chart, in your own lighting, which is worth more than mine. For production jobs, the pre-stuffed mixed bags in 5", 12", 18" and 36" save the hour.
