Fabric Grain Stretch Test
- Cut a small square of cotton fabric with edges parallel to the straight grains.
- Tug on the fabric side to side, along one straight grain, then tug from the other direction. Do you feel and see a difference? Did you notice slightly less stretch in one direction? That was the lengthwise grain.
- Now tug on the square from corner to corner--along the bias. It probably stretched quite a bit, and if you tugged too hard it may have become permanently distorted.
