Hi All

I am new to the forum as I am looking for some advice.
I have been asked if I would like a stall at a local event (classic & supercar show) which has around 60 other stalls and a kids fair.

My question is how many balloons roughly do I need? I don't want to buy lots of stock and end up not selling much, but at the same time I'm worried about selling out quickly.
I was thinking of buying mainly foil balloons which kids could write their names on in glue/glitter etc to personalise them and then a selection of character balloons (any advice on which you find most popular would be amazing!)

any help would be much appreciated.

thanks in advance charlotte
