To calculate how much fabric you need for borders, backing and binding for a quilt, begin by entering the width and length of the quilt top. Be sure to take your measurements accross the center of the quilt top. If measurements at the edges differ from those at the center, ease the borders while sewing. This helps to square up the quilt top and keep the borders from being wavy. Select a border style and enter your planned border widths and fabric widths. For borders not included in your quilt top, set the width to 0. Then click the Calculate button.
