What is this called?

[Frodo]

I just started doing this to dress up the edges of chrome tan

Lay a2” wide piece on

the edge finish side to finish side

sew along the edge 

ffold the piece over and under
sew along the top edge of the fold to secure

if you make the fold over wider it can be used as your gusset also

@Frodo The pic bottom right, looks like something I have done with binding on horse rugs( I don't have a binder) . Sew the edges together on the inside, fold right over and sew outside.  Whatever you've done, it looks  very neat   As for 'what is this called'....dunno....binding? Nice colours too.

When my wife does that on her quilts it's called binding.

Somewhere on here is a good tutorial on that type of binding from several years ago.  Here's one of them, although not the one I was thinking of.  It's a variation of a French Rolled Edge binding.
