Piping on three sides of a pouch

[Aparecium]

I'm making a zipped pouch and I want to put piping on three sides. I can't quite figure out how to finish the piping. The only thing I can think of is to curve the piping so the ends disappear into the seams just before the corner. Not sure how that will look. All my online searches bring up how to finish piping by joining the ends. Any advice?

Any crafters who can advise?

thats how I have seen it done on cushions. I would leave the filling out of the piping at the ends though and just run the casing into the seams of it will be bulky and make a messier seam.

Oh thank you, that's a good idea!
