Laying the fabric was the easy part, the koi are very curious.
Gathering the rock I have stashed all over the garden was the hard part.
I take that back, carrying each rock across this narrow wall was very difficult and could have been a really bad experience.
Tried like heck to use the rock we had but the last flagstone was just to small to work, no matter which way I flipped it.
A quick trip to the quarry and the new flag fit like a glove.
These Koi really are very curious creatures.
The finished waterfall. Enjoy!
