Nor should she ever fear to unpick her work; for only by experiment can she succeed in finding the best combinations, and, one little piece ill done, will be sufficient to spoil her whole embroidery, as no touching-up can afterwards improve it.
We have now named the principal stitches used in hand embroidery, whether to be executed in crewel or silk.
There are, however, numberless other stitches used in crewel embroidery: such as ordinary stitching, like that used in plain needlework, in which many designs were formerly traced on quilted backgrounds—others, again, are many of them lace stitches, or forms of herringbone, and are used for filling in the foliage of large conventional floriated designs, such as we are accustomed to see in the English crewel work of the sixteenth and seventeenth centuries, on a twilled cotton material, resembling our modern Bolton sheeting.
It would be impossible to describe or even enumerate them all; as varieties may be constantly invented by an ingenious worker to enrich her design, and in lace work there are already 100 named stitches, which occasionally are used in decorative embroidery. Most of these, if required, can be shown as taught at the Royal School of Art-Needlework, and are illustrated by samplers.
