Where to buy garden stone ball?

[MrChips]

Something like these stone (or stone effect) balls:






I've tried a few local garden centre type places but no joy!!

This is the current state of our front "garden" so am looking for a few bits to add into the pebbles. I've got a few plants already, and planning to either get some nice pots to go under the bay window, or to build something out of sleepers to hide the gas meter away a bit more. Other ideas very welcome!

You might want to consider this kind of thing to hide something away.

Obviously, don't buy that one as it costs billions in postage. I've seen similar for about £50 in garden centres.

I think it would work far better than a stone ball with the pebbles you've put down.
