Measure the quilt top lengthwise through the center and along both edges. Average the three measurements. Cut your border fabric length the average measurement. Mark the center and quarter points of the quilt top and the border fabric. Match markings and pin your border fabric to the sides of the top. Sew the border to the top. Repeat for the top and bottom borders. Applying borders in this manner helps avoid wavy borders and pleats or puckers when quilting.
