if you didn't, i highly recommend you use one for future borders.
they are also very helpful when attaching binding.

i never cut my border strips across the width of the fabric. (weft/woof)
i cut up the length of the fabric. (warp)

this will sometimes mean additional piecing to get borders the length i need, but it's well worth the effort.

the woof/weft stretches.
the warp does not.

little saying to help me remember:
the fabric's warp will not [warp].
