love the interview thank you for posting it vicki . such a beautiful relaxing rooftop retreat . it makes me wish i lived closer so i could come show you the best ways to go about your indoor water feature . i have pretty much any woodworking tool there is . so i am sure i could have you going in no time . just curious if any of you have ever used expanding spray foam ? it makes awesome fake rock as well as fake tree's and limbs . and can be water proofed or covered with cement , quickwall or hypertufa .
