Thanks, x3! Yes, Greg, I've tried to repurpose as much stuff as I could. So much cooler if home made although some of it was purchased, THEN repurposed. LOL! Way more on that in another discussion on this forum about "little things." There's a big styrofoam block under the tile, much less weight and more stable than having more soil under there. A dry spot in the middle sounded like a good idea too.
I've been picking up rocks that catch my eye for 40 years. This is a cool way to 'use' some of the smaller ones.
No much is getting done here lately. It's just raining all the time. And the mosquitoes, OMG!!
