Fabric cut on the bias has more stretch than fabric cut on the straight of grain. For this reason, bias tape easily fits around corners and curves.
To make yards and yards of continuous bias tape, lay out fabric and cut off one end at a 45-degree angle. Sew this cut piece to the other end. See Diagram #1.
On the reverse side of the fabric, mark off the desired bias tape width parallel to the 45 degree edge. (Diagram #1 shows five strips but mark as many as your fabric will allow.)
Place the two lengthwise edges right sides together and offset both ends the desired width of the finished tape. For example, for 1-1/4" tape, offset piece #1 and #5 (shown in Diagram #2) 1-1/4". Sew a 1/4 " seam along the length of the fabric creating a spiraled piece of fabric.
Cut along the marked lines in the spiral starting at the line between #1 and #2 and continue to the end.
To figure how much bias tape you will get out of a piece of fabric:
(1) Measure your piece of fabric that you are going to be cutting your bias strips from.
(2) Now multiply the measurement of the fabric by itself to get the squares inches of the area.
(3) Then divide the squares inches by the desired width of the bias strip.
For Example :
Square = 12"
So 12 x 12 = 144 square inches
Bias Tape Width = 2"
Therefore, 144 / 2 = 72 " of 2" wide bias strips from a 12" square
Cutting fabric on the bias means cutting it at a 45-degree angle to the grain of the fabric. This allows the fabric to stretch and drape more easily, creating a fluid and drapey garment. To cut fabric on the bias, fold the fabric diagonally and cut along the fold. Be sure to handle the fabric carefully to prevent stretching or distortion.
Cutting fabric on the bias allows for more stretch and drape in the material. This is because cutting on the bias means cutting at a 45-degree angle to the grain of the fabric, which allows the fabric to stretch and drape more easily. The benefits of cutting on the bias include creating garments that fit better, have more movement, and drape beautifully on the body.

BIAS
Cutting on the bias means cutting fabric at a 45-degree angle to the grain. This allows the fabric to stretch and drape more fluidly compared to cutting along the grain. The bias cut creates a softer, more flowing look as the fabric follows the natural curves of the body.
Bias is a noun in that sentence.
(n) a line on the weave of fabric
Fabric chalk
Fabric cut along the bias has stretch and allows it to go around curves
"Cutting on the bias" means cutting fabric at a 45-degree angle to the straight grain. This technique allows the fabric to have more stretch and drape, making it more fluid and flexible compared to fabric cut along the straight grain.
That is the bias. When you have a pattern that states "cut on bias" the pattern piece would be placed in a fastion that would be a "diagonal line against fabric grain". Pattern pieces cut in this fashion are sometimes more difficult to sew because when fabric is cut on the bias it gives the cut edge more of a stretch.
