Lewis

Model

17-10

Machines

are

adjusted

at

the

factory

for

2-to-1

stitching.

By

this

we

mean

that

every

second

stitch

pene-

trates

the

lower

fabric,

producing

a

stitch

similar

to

hand-felling.

This

kind

of

stitching

is

generally

used

for

felling

facings

and

botfoms

of

quarterlined,

half

lined

and

skeleton

lined

coats.

The

2-to-1

stitch

appears

under

the

binding

(see

illustration).

It

may

be

used

with

equally

good

success

on

edges

finished

either

with

piping

or

turned

under.
