Well, that kitty is sure fetching! The paw is pointing to a flange, if it is a folded piece of fabric with nothing inside. It is piping if it has a cord inside. It is a beautiful quilt!
Even we here in the US have different names for things in different areas of the country. If that skinny orange thing is dimensional, that is if you can stand it up and it is only sewn on one side, then most would call it a flange. :lol:
