Schmetz introduced so-called self-threading or handicap needles to make threading much easier and quicker. These needles are especially useful if your sewing machine doesn’t have a built-in threader.

What Will Happen If The Machine Threading Is Incorrect?

It’s important to thread the sewing machine correctly to work smoothly and avoid issues during sewing. For example, your machine might develop thread bunching, skip stitches, make variable stitches, or you may notice seam puckering.
