Castellated Hose

[JPS]

One thing that stands out to me is that when we talk about castellated hose, there are two different ways of achieving the look. Richard, you posted a picture of your own hose, which are meant to create a castellated top, but here, there's another method, folding down the top to create only the appearance of a castellated hose behind a contrasting foreground (for the record, I think this looks a bit neater). I wonder if one of these predated the other, or whether they developed independently of one another.
