Looped embroidery Stitches are also called "Pile embroidery Stitches”. These embroidery stitches create a texture which gives the 3-D look. The mound surface is created by the loops contained in the stitches. Some stitches remain with the loops intact and some require the loops be cut. Usually looped embroidery stitches are generally used in rug making and they may also be used in any needlepoint project that requires a 3-D or mound look. Some of the more interesting looped embroidery stitches include the loop stitch, the shell stitch and the velvet stitch.
