Grain lines
A few years ago I thought I had gotten a super deal on a shirt at an outlet store. Every time I wore the shirt it would twist and go to one side. No matter how much I ironed and "fixed" the shirt it just wouldn't cooperate! Now I know that shirt was cut off grain and I didn't get a good deal on it!
In Chapter 3 of Gertie's New Book For Better Sewing Gertie's teaches us a few methods to get the fabric on grain before we begin working with it. Once the fabric is on grain we need to make sure it stays on grain when we cut out pattern pieces. To do this, always place the pattern on the fabric with the grain line parallel to the fabric's grain. Measure the distance form the pattern's grain line to the edge of the fabric at various points on the pattern's grain line to make sure it is the same distance at every point.
