Helium balloons are a versatile popular option for easy positioning and DIY transport to a venue so they can be used for both a party and another celebration at home.  They are easy to customise in any colour scheme or theme.  The prices above give a sense for the size of bunch you can get for your money. I always treat latex balloons with hi float so that they last at least 5 days.  Foils usually last longer at room temp. If you send me a photo of another display you like, I can usually replicate it. I can deliver helium balloons in Cobham and the local area or have them ready for easy drive through collection. SIngle helium balloons attached to a sweet-filled box or a small weight to decorate a chair double up as going home gifts for parties.
