Grainline is very important. When on garment is on-grain by the home sewer it really looks great whereas so many garments purchased now days look awful because of the poor attention to grain lines.Made at home does not imply inferiority and I do not understand this concept of 'homemade'. While quilting fabric can be ripped in either direction I usually measure lengthwise borders from the selvedges because they are on grain already and not have loss that needs to be trimmed away. I frequently rip the crosswise grain and then it is easy to tenter (pull diagonally) to straighten the fabric to cut my pieces. Over a period of time I have come to a point of using the lengthwise direction to cut pieces because it does have less stretch than the crosswise grain.
