you still have to line up the fabric to make sure there aren't any wrinkles (that it is straight)or are you folding the fabric
with the sides matching of what you just ripped and you cut from there?
If fabric is ripped, it tears on the straight of grain. By that I mean it rips along one grain (between two horizontal thread lines) of the fabric.
Fabric is woven with 1/2 of the threads going horizontal and 1/2 vertical. If you are able to line it up so that the crosswise thread are at 90 degrees to the length wise threads, then your fabric is "straight", which is a perfect scenario.
Most all the methods that are described are attempting to straighten fabric so that the vertical and horizontal threads are at 90 degrees to each other.
