Unlike wide decor piping, which is hand-sewn or glued to a finished project after completion, narrow piping is stitched in place before the project's final construction.
Narrow piping is available pre-packaged or by-the-yard at any sewing center. Piping should be stitched in place using thread to match the color of the piping.
To stitch piping to a blocked piece of needlepoint, lay the piping into position having the rounded edge facing the inside of the project to the left of the ditch. Stitch the piping in place along the ditch using the zipper foot of your sewing machine. A zipper foot allows you to stitch very close to the edges of the needlepoint stitches and guides you along the ridge created by the needlepoint stitches. Clip into the piping at the corners to avoid rounded corners.
