It's a double layer of heavy duty black polythene Gertie - which I already had. I used some plastic coated bubble wrap, that a settee came wrapped in, for the lining along with some sand. Hole was dug out to about 18"/24" at the deepest and sloped up to the right hand side with a little beach. There was a dead tree which I'd previously removed, but we couldn't get the roots out, so I just incorporated it into the planting area on the right. Oxygenators and plants were put in last autumn with some watercress in spring.
Dug out last summer and rocks etc put in place:
Filled and some planting put in :
Most recent pic this summer:
Hope that's of some use
