Experiment with your fabrics. Lay your border fabrics next to your quilt top and play around with the arrangement, flipping them back and forth and trying different widths until you find a combination that suits you.
If you use a border print, be sure to allow a 1/4" seam allowance on each side of the stripe when you cut it out.
I don't want to miter my border stripe and I don't want the edges to butt against each other where they meet at corners, so I'll add fabric squares at the corners of the inner border. If you would like to do that, cut squares with sides that are equal to the cut width of your inner border.
My border print isn't quite long enough to extend the entire length of the table runner, so I'll need to piece the long borders. To do that, I'll cut two segments of border stripe in exactly the same way and then place the stripes right sides together, pulling one along the other until their motifs match exactly. I'll use a pin to keep fabrics from shifting as I cut across the borders, and then I'll sew the two together with a 1/4" seam allowance, measure my quilt and cut the border to match.
Use my quilt border instructions to measure the table runner and sew on its borders. For more about corner squares, refer to borders with corner squares.
