How to make and sew together 200 inches of continuous bias binding from a half yard of fabric. Bias binding strips are used to cover cording or welt. Covered cording can be used on pillows and cushions, as well as sewn to the edges window treatments and valances. By creating a continuous length of bias strips, less fabric is used than when cutting longer strips and sewing the strips together individually. Continuous bias strips are not cut on the exact bias, however. This makes this method less desirable when pattern placement is critical on the bias strips, such as with print fabrics. Cutting continuous bias strips works well for solid fabrics and when there is a fabric shortage, however.
