THE TUCKER
The Tucker is a time-saver for
making tucks up to one inch in
width. Two adjustable scales are
provided, the smaller near the
needle is numbered from 1 to 8, ex­
pressing in eighths of an inch the
width of the tuck. The larger scale
expresses in quarter inches the
spacing between tucks.
Set the tuck scale first for the
width of tuck. The space scale is
then adjusted using the needle as an
indicator for the spacing between
tucks. When both scales are set at the same number, blind tucks result. That is, the
fold of one tuck just touches the stitching line of the next. When additional space
between tucks is desired, adjust the space scale to a point beyond the tuck scale reading
equal to the spacing desired, expressed in quarters of an inch. Thus half-inch tucks spaced
a half inch apart require a tuck scale setting of 4, and a space scale setting of 6,
