Fabric Bias can be confusing to a beginning sewist. Cross grain, length of grain, and bias are all terms that experienced sewists know but beginners find hard to understand right away. Alex explains that straight of grain is used for both the cross grain and the length of grain. She also tells about the amount of stretch involved in those directions. But it's the bias that is the dangerous side. You need to know what the bias is and how that changes how you use it in sewing and in quilting. The directions of the grain affect placement, colors, and pressing.
Here's a quick test:
- What is the direction that is 90 degrees to the selvage called?
- What is the direction that is parallel to the selvage called?
- How much stretch is there in the cross grain?
- How much stretch is there in the length of grain?
- How much stretch is there in the bias?
- What is the selvage?
Be sure to forward this to new sewists so they start with the understanding of cross grain, length of grain, and bias.
