Wow, Kathy, even cooler than the Flamingo, is the dock and the river in the background. Looks like an awesome place!
I think that's a great idea to cover the Flamingo in Semps. They don't need a lot of water, and you could stuff the Flamingo body with soil. You could even maybe use the coir fiber mats that you can buy in bulk off a roll and cut it to fit the Flamingo frame. Then just poke a hole in each place that you insert the sempervivum roots.
