I don't know if I missed what it looked like before or if I just don't remember (either is equally likely) but it looks pretty good!

Though I was staring at your rocks and thinking about having to get Youngest to move this HUGE one I found in one of the smaller garden beds when I was commencing Floral Experiment #2. I managed to dig it out (it was in the "wrong spot" for the border and turned out to be alot bigger than I thought) and roll it away but when I went to pick it up later it was going to be a lot more effort than I wanted to put in so I asked Youngest if he was able to move it and he straight up laughed at it, hefted it up no dramas and asked me where I wanted it XD It's now near the tree bed where it might replace another couple of rocks under one of the philodendron(?) leaves if I need anymore.

Anyway that border is lovely :D

The corrugated sheet looks really classic :)
