Pond fashioned from...
I'd like to put a small water feature/pond in my garden but I'm a bit devoid of ideas, please help inspire me! I quite liked the idea of getting an old Belfast sink and using that. It's essential that it be safe for children but I can't even seem to find wrought iron grates to cover ponds (not on any kind of limited budget anyway). I thought I could put a rock/plantation in the middle so there's no gap for them to fall in but still enough water for children to see a few beetles swimming around and perhaps provide a drinks for bees and so forth. I'm worried that it might just fill with leaves and be, well, rubbish! If it's not obvious by now, I've no idea what I'm doing!
What unusual objects or ideas have people used for small ponds?
