If the fabric is not stretched tight in the frame, the
pattern may be sewn incorrectly or there may be
shrinkage of the pattern. Hoop the fabric correctly
in the frame.
Always use stabilizer material, especially with
stretch fabrics, lightweight fabrics, fabrics with a
coarse weave, or fabrics that often cause pattern
shrinkage. Contact your authorized dealer for the
proper stabilizer.
If the frame bumps something during sewing, the
pattern will turn out poorly. Do not place anything
in the area where the frame may bump it during
sewing.
Rehoop the fabric in the embroidery frame so
that excess fabric is away from the sewing arm,
and rotate the pattern 180 degrees.
Place a thick book or similar object under the arm
head to lightly lift the heavy side and keep it level.
If fabric is hanging off the table while
embroidering, the embroidery unit will not move
freely. Position the fabric so that it does not hang
off the table or hold the fabric to keep it from
dragging.
Stop the machine, and then correctly position the
fabric so that it does not get caught or snagged.
If the presser foot is bumped or the embroidery
unit is moved during sewing, the pattern will not
turn out correctly. Be careful when removing or
reattaching the embroidery frame during sewing.
Adjust the thread tension.
Use the embroidery needle plate cover.
Change the bobbin case or bobbin thread so that
the correct combination is used.
