To Turn a Corner

die work as desired, using die noodle as a pivo'
(lion lower die pro.ssof fool.

To Regulate the Pressure on the Material
For ordinary family .sewing it is seldom nooos.sary
to oliaiigo the prossuro on llio material. If sowing
lino silk or lliiiisy inalorial, liglilen the prossuro by
turning tho dunnb sorow (C(t, Fig. 7, page 10) on
die lop of dio maohiiio ovor to Iho lofl. To inoroaso
the prossuro, turn this Ihunib sorow ovor lo the rigid,
d'lio pressure should be only heavy enough lo
lirevont the inalorial from ri.sing with tho noodle
and lo enable llio food to move the work along
evenly; a heavier prossuro will make tho inaehine
run hard.
To Sew Flannel or Bias Seams
Vise a.short slileh and as light a lonsion as iiossiblo
on the noodle throad so as lo leave the thread loose,
enough in the seam to allow the goods lo strololi if
noecssary.
A Stitch to Ravel Easily
can bo made if desiirod, by having the tension
on llio noodle thread so light (hat the bobbin thread
will not draw into the goods but lie straight, as
she rii in Fig. 17, page 17.
