I was visiting Margaret Simpson to get a piece of her lotus a few weeks ago and she showed me her latest water garden that was made from an old bathtub. I've noticed an old one in the woods on the right of the drive. Would anyone be interested in making our own water garden. We have lots of goldfish and I'm sure we can get plants. It would make the space even more gorgeous than it already is.

I also have a book on this topic. Cheers. Lisa
