Temporarily blocking off a drive that has no gate?

[ladders]

Ok not really gardening keeping but you are all women with good ideas! Friend having c
Christening at Granparents house. Drive goes onto road - but no gate, no side gate and no facility to put one in. Either side of gate are brick pillars so thinking of some kind of fencing or mesh/screening that can be put up and taken down as needed. I know chldren should be watched but there is always one that escapes!
Ideas please!

We have that problem but with a small dog. My husband made a frame and fixed chicken wire into it with a staple gun. It did the trick, was very cheap and light too. When not in use, we just slide it to one side.

Or if you want something more decorative, there's split bamboo screening which could be attached to a frame. Or trellis panels. Chicken wire would be lightest and cheapest, though.

my mum blocks her drive with an old childproof fireguard - not really the look you want if there's guests though...

Great ideas I will pass them on - thanks

Would this be worth the investment? Could it be used for other things?
