Very nice! Thank you for the idea :)

Fabulous! The only thing that might create work for you is pesky weeds finding their way thru brick holes/openings. No biggie if you are proactive about it and going by other pics you've shared, you seem to be very into neatness, so no biggie.

Yes, I thought of that, but I walk through the garden so many times a day, I'll be able to stay on top of them. You know what they say about people that keep a neat house.......they tend to keep a neat yard. I confess I do both when I can. ;)

If the brick holes line up you can always put a rebar rod through them and drive it into the ground. Rebar is cheap at big box stores and i find them pretty useful around the garden.

Excellent idea! I actually have some rebar on hand. I could check it out. I kind of doubt the holes will be lined up. Luck is usually not on my side that way. But honestly, I don't think they are going to be going anywhere. Someone would have to intentionally kick them down or fall over the thing I think, to bring any of them down. Water nor wind will bring them down. Also, it's right by a vicious, thorny, mature KnockOut rose standard, so I don't tend to walk around that area much. I hate thorns and were it not that the previous owner loved them and planted so many, there wouldn't be a one in my yard. I only like thorny bushes from afar. :)
