I think I mentioned that I've been ripping fabric strips for my lanyards, rather than cutting them, in order to make sure that the pieces are lined up along the grain lines. And this got me thinking about fabric grain in general...
I pay moderate attention to the grain of my fabric. If it's possible (say, a cotton print), I rip both edges of the fabric before folding it in half and laying down the pattern pieces. And I do make sure to align the pattern pieces with the grainline as directed. For example, I cut out the waistband of the circle skirt that I am making along the bias, as directed.
But if I can't rip the edges, then I don't do that thread pulling thing. And I've never tried to fix fabric that was off grain. (You do it with a steam iron, I think...)
So, how about you? How much attention do you pay to grain line in your fabric? Do you make sure to align your pattern pieces along the grain line as specified? Do you check to see if your fabric is on grain? Do you rip edges and/or pull threads to find the grain line? If your fabric is off grain do you try to fix it? How do you fix it?
