Running is done by passing the needle in and out of the material at
regular intervals. Small, even stitches and spaces should follow
consecutively on both sides of the material. The stitches should be much
shorter than those used for basting, the length being determined largely
by the kind of cloth used.
When running is combined with a back-stitch, two or more
running-stitches and one back-stitch are taken alternately. The
back-stitch is a stitch taken backward on the upper side of the cloth,
the needle being put back each time into the end of the last stitch and
brought out the same distance beyond the last stitch.
