As above really, I want some edging for curved flower beds. DH suggested the metal but I’ve never seen it in person so can’t imagine how thin/soft it is, does it have a sharp edge?
Thé alternative is probably wood on a roll, I’m guessing the main disadvantage is that it will rot. I’ve discounted brick/stone as DS 3 loves diving to the ground playing ball in that and I’ve worried he’ll bang his head on them.
