  • Making continuous piping strips / bias binding

    To calculate how much binding a square of fabric will produce:

    length = area of square divided by width of binding strip

    Example:

    For a 20" square, area = 20" x 20" = 400" square inches
    binding strip width = 2"
    400" square inches area divided by 2" width = 200" binding

    To estimate how large the square must be to produce the binding length you need:

    1. Multiply the length of the strip needed by its width to find its area.

    2. Determine the square root of the area to estimate the square size needed.

    Example:
    Strip needed is 2" wide by 250" long
    2" x 250" = 500" square area
    square root of 500 = 22.36
    Round up and cut a 23" fabric square

    The continuous binding method works best with larger pieces of fabric, because using small squares produces binding with many bulky seam allowances along its length.
