For both tup and bottom embroidery thread No. 60-80 is used, which gives the heat
results in even sewing around holes. For hole embroidery the thread tension is of utmost
importance. The bottom thread tension should be slightly higher than that of the top
thread, so that the thread knots will only show on the lower face of the material.
The slide in the embroidery plate should be so positioned that the needle, when effecting
a right-hand stitch, enters in the recess of the guide pin just beyond the edge of the
material. This setting is altered according to stitch length and should therefore be
repeated. Then allow the machine to opei ate at regular speed, at the same time turning
lib
the embroidery ring three or four times around the guide pin at the same regular
speed in clockwise direction. Then set zigzag knob 12 (Fig. 2) to zero and secure the
thread by a few stitches. These binding stitches should be parallel to the embroidery
stitches SI) that they icniain practically invisible.
When the slide of the embroidery plate is reversed, as shown in Fig, 77, the guide pin
can be used as a centre in sewing circular embroidery. The needle stitches through the
elongated slot of the slide. By ehanging the stitch width, i. e. varying the speed of rota­
tion of the enibroidery ring during the stitching, or by the use of threads of different
euluurs, vary attractive and varied patterns can be produced.
When embroidering around holes, observe the general rule that holes of the same size
should be finished successively so that the slide need not be changed too frequently.
