Darning

Put

the

needle

in

its

highest

position

and

re

move

the

presser

foot

ankle.

Attach

the

darn

ing

foot

to

the

machine

making

sure

that

the

arm

of

the

foot

rests

on

the

needle

screw.

Set

the

sewing

machine

for

straight

stitch

as

a

wide

zigzag

stitch

might

break

the

needle.

Drop

the

feed

dog.

Decrease

the

top

thread

tension

slightly.

Darning

with

the

darning

foot

is

done

by

free

hand

and,

therefore,

requires

some

practice.

it

is

easier

to

darn

if

the

fabric

is

stretched

in

a

hoop.

When

stretched,

the

fabric

should

lie

flat

on

the

machine.

Place

the

hoop

under

the

darning

foot.

Lower

the

presser

foot

and

bring

up

the

lower

thread.

Begin

by

sewing

back

and

forth

over

the

hole

with

long

stitches.

Since

the

feed

dog

is

dis

engaged,

you

guide

the

hoop

back

and

forth

by

yourself

and

thus

determine

the

stitch

length.

The

faster

you

move

the

hoop,

the

longer

the

stitch

will

be.

Keep

the

machine

speed

uniform.

Continue

in

the

same

manner

until

threads

have

been

stitched

across

the

entire

hole.

Then

turn

the

work

9O’

and

darn

across

the

hole

with

short

stitches

which

are

obtained

by

moving

the

hoop

slowly

back

and

forth.

Keep

the

machine

speed

uniform.

if

the

hole

is

large,

cover

it

with

guaze

and

then

darn

as

described

above.

Darning

can

also

be

done

on

the

bias

of

the

fabric

or

in

circles

if

this

would

be

better

adapted

to

the

structure

of

the

fabric.
