Cut the Fabrics Measure the width of your table to determine the length of your runner. Add 20 inches for 10-inch drops and 1 inch for 1/2-inch seam allowances. Cut the houndstooth 13 inches wide by the length measurement. Cut the toile 17 inches wide by the length measurement.
Sew the Runner With right sides facing, sew the toile and houndstooth pieces together along one long edge. Match the remaining long edges and sew the seam. Press the seams toward the houndstooth. Lay the runner so the houndstooth is centered on top. The toile will form a border on each side. Press the runner, folding under the seam allowance on the short edges. Use hem tape to finish the ends. Topstitch close to each seam through all layers.
Add the Ruffles Cut two 28-inch lengths of each ribbon. Place a yellow length on top of a black length. Roll and sew a 1/4-inch hem on each short raw edge. Sew a gathering thread down the center of the layered ribbons. Gather the ribbon to fit the short end of the runner. Repeat with the remaining ribbons. Pin the gathering line of each ribbon 1-1/2 inches from each short edge of the runner and stitch in place.
