Thread tension
To ensure perfect sewing and a durable
seam, the top and bottom thread-tensions
must be well adjusted to each other and
the threads must be interlaced between
the two fabric pieces. The interlacing
should be visible from the underside of
the material only when sewing decorative
seams, buttonholes and darning.
