ILLUSTRATION 70.--This shows the back stitch, the working of which
is well known; it is worked in several rows close to each other.
ILLUSTRATIONS 71 & 72 show another kind of back stitch, called
point croisé, which is only used on very thin and transparent
materials. This stitch forms on the wrong side a sort of darned
pattern, which is seen by transparence on the right side, and gives
the embroidered pattern a thicker appearance, contrasting with the
rest of the work. For this stitch insert the needle into the material
as for the common back stitch, draw it out underneath the needle on
the opposite outline of the pattern, so as to form on the wrong side a
slanting line. Insert the needle again as for common back stitch; draw
it out slanting at the place marked for the next stitch on the
opposite outline, as shown in illustration 71.
ILLUSTRATION 73 shows the knotted stitch; the simplest way of
working it is to work two back stitches at a short distance from each
other over the same thread.
The knotted stitch seen in ILLUSTRATION 74 is worked thus:--Take
about four threads of the material on the needle, draw the needle half
out, wind the cotton twice round the point of the needle, hold it
tight with the thumb, draw the needle out carefully and insert it at
the place where the stitch was begun, and draw it out at the place
where the next stitch is to be worked.
The knotted stitch seen on ILLUSTRATION 75 is worked in nearly the
same manner as the preceding one. Before drawing the cotton out of the
material hold it tight with the left-hand thumb; leave the needle in
the same position, wind the cotton twice round it, turn the needle
from left to right, so (follow the direction of the arrow) that its
point arrives where the cotton was drawn out (marked by a cross in
illustration), insert the needle there, and draw it out at the place
of the next stitch.
