Continuous
Bias Binding

- Cut
a square of fabric the size calculated to produce the length of binding
required.
To
calculate how large the square must be:
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 100" long
2" x 100" = 200" square area
square root of 200 = 14.14
Round
up and cut a 15" fabric square
-
Mark
two opposite edges, (Diagram 1) then cut the square diagonally from one
corner to the other.
- Place
the two pin-marked edges right sides together, raw edges aligned and
triangle nubs overlapping equally at each end. (Diagram 2)
- Sew
the segments together with a 1/4" seam allowance. (Diagram 3)
- Use
your ruler to mark cutting lines parallel to the long edges on the reverse
side of the fabric, spacing the cutting lines to equal the width of the
required binding strip. (Diagram 3)
- Make
a tube by bringing the right sides of the fabric together, offsetting the
ends by one line making sure the lines match each other exactly. Sew the
ends together with a 1/4" seam allowance (Diagram 4)
- Start
cutting from the offset corner side of the tube, directly on a drawn line.
Continue cutting around the tube until you have one long strip of bias
binding.
- Press
open seam allowances
