Welted Edge: A welted edge on a pillow is a decorative trim or border that tapers and is sewn onto the edge of the pillow. It's also known as piping and cording.
Knife Edge: Knife edge pillows are very simple. They have no fancy details on the edges—just fabric sewn together to make sharp corners. These pillows give a clean, modern look that fits with any decor.
Fringe: A decorative border or edging of hanging threads, cords, or strips, often attached to a separate band at the edge of a pillow or throw.
