SINGER 101-12 - Manual (Page 29)

To increase the length of stitch, turn the feed
regulating disc (D) over to the right until the
number of the desired length of stitch is nearest to
the point of the arrows To shorten the stitch, turn
the feed regulating disc over to the left rnitil the
number of the desired length of stitch is nearest
to the point of the arrow.
To Regulate the Pressure on the Material
For ordinary family sewing, it is seldom necessary
to change the pressure on the material. If sewing
fine silk or fiimsy material, lighten the pressure by
turning the thumb screw (A, Fig. 29, page 29) bn
the top of the machine over to the left. To increase
the pressure, turn this thumb screw over to the right.
The pressure should be only heavy enough to pre­
vent the material from rising with the needle and to
enable the feed to move the work along evenly; a
heavier pressure will make the machine run hard.

To Sew Flannel or Bias Seams
Use a short stitch and as light a tension as possible
on the needle thread so as to leave the thread loose
enough in the seam to allow the goods to stretch
if necessary.
A Stitch to Ravel Easily
can be made if desired, by having the tension on
the needle thread so light that the bobbin thread
will not draw into the goods, but lie straight, as
shown in Fig. 26, page 25.
