Tension

Regulation

Balanced

tensions

are

essential

for sewing.

If

your

tension

is

correct,

you

will

hove

perfect

seams

os

sketched

below

(Ill).

—

The

threads

interlock

on

the

underside

of

the

fabric.

Cause:

Upper

tension

too

loose

or

lower

tension

too

tight.

The

threads

interlock

on

the

surface

of

the

fabric.

Cause:

Upper

tension

too

fight

or

lower

tension

too

loose.

To

check

whether

the

tensions

are

correctly

bal

anced,

take

a

closely

woven

piece

of

fabric

and

sew

a

few

straight

and

zigzag

seams,

If

the

straight

stitches

are

tightly

drown

in

on

both

sides

of

the

fabric

(see

seam

sketch

Ill),

the

tensions

are

correct.

The

surest

way

to

double-check

this

is

by

eyomining

a

zigzog

seam.

If

the

zigzag

seam

is

equally

wide

on

surface

and

underside

of

the

fabric,

that

is,

if

the

threads

are

locked

exactly

at

the

zigs

and

zags

of

the

seam,

the

tension

ad

just

ment

is

correct.
