Proper Tension

Upper Thread Tension Too Loose

Upper Thread Tension Too Tight

A perfect straight stitch will be formed with both

threads interlocking in fabric as shown in Fig. 1.

When using the zig zag stitch for embroidery

(satin stitching), decrease upper tension so that

top surface will look smooth at the expense of the
bottom surface.
