Let's talk about grain and off-grain.
I was just reading about someone's bad experience with fabric shrinking and it got me thinking about the grain of fabric and how I haven't seen a topic on straightening fabric with the grain. I know some of you tear fabric to straighten but I'm not comfortable doing that. I try to match selvage to selvage and see if my fold is flat and if not straighten it from there. But as I do this sometimes I can see the design run crooked. Do I straighten by design or the fold? Batiks when straightened by fold are almost always very wavy at the selvages. How do you know when the grain is straight?
