Did you know that there is a right way and right way of thread also. I learned in EGA years ago that if you are hand sewing and your thread tends to curl or get knots rethread it the other end and it will stop. We were told that thread made in Europe arrives here on huge cones and is rewound onto spools and is often wound onto the spools where it comes off the wrong way. Wouldn't have believed it but it works. I can't look at it and tell right from wrong but some swear they can.
