As a May Bank Holiday project I decided to build a small & long waterfall at the side of my house. I dug out the base, lined it with sand and then I've used pond liner. I've then come to decorate it and this is where the issues started... I can't cover the pond liner!
I've tried and tried, but I can't cover it up effectively. I'd love to know if anyone has tried anything similar before, and how they managed to finish it off.
Here's a picture which hopefully indicates the issue I'm having.
