In general I would not suggest stitching to work with non-wovens. I would rely more on tape or other joining techniques. But in the event that stitching is used I can see the point in using a zigzag as opposed to a straight stitch.
I may be slow... But I sure am gimpy.
"Bless you child, when you set out to thread a needle don't hold the thread still and fetch the needle up to it; hold the needle still and poke the thread at it; that's the way a woman most always does, but a man always does t'other way."
