Well I seen a couple of DIY shows where they roll the end of the liner into a 2 x 4 and secured the 2x4 to the side of the frame of the pond and use plants around it to cover it. Hope it helps. I was planning on doing a pond but kinda put the idea on hold due to planning on put a pet store. Yay. I just visit one that is owned by a family and they asked me about $350 grand for it but there's a lot of work to do on it to put it up to date.
