Figure F-2. Thread Direction and Stretch Characteristics of Fabric.
d. Straight Cut and Bias Cut Patches. When fabric patches without stretch are required, cut
the patch so that the edge of the patch runs in the same direction as the threads. The edge of the patch
will run parallel to the edge of the material. When a patch that stretches is required, use a bias cut patch.
The edge of a bias cut patch will run at a 45 degree angle to the edge of the material. A bias cut patch
has 30 percent more stretch. Straight cut patches and bias cut patches are shown in figure F-3.
