This design could well be in the Bird group, but since it consists of two mirrored strips, it really belongs here. This design makes some very striking frames, depending on what you choose for the corners. (A mirror is helpful for doing this.) Check The Paper News no.6 for details about designing frames with the Borders.
Size of each strip: 1.375" x 3.75" (3.5cm x 9.5cm)
