piping?
These patterns all call "folded borders" what I have always called piping.

What sampler pattern are you making? Do you have a picture? Is there piping anywhere on the quilt?
Maybe piping is generally really, really thin - or corded, almost. And the term "folded border" refers to a wider (1" or more) exposed flat piping.
Maybe.
