Cut your burlap to the desired size for the table runner and placemats. To prevent fraying, apply a thin line of glue or stitch around all edges.
Lay out your lace trim along the perimeter of each placemat and along both long edges of the runner. Then adjust to ensure the lace lies flat and even.
Secure the lace with pins, then sew or glue it in place. If sewing, use a straight stitch about ¼ inch from the burlap edge.
For a layered look on the runner, add extra lace or ruffled burlap at both ends, folding slightly to create soft gathers.
Press lightly with a warm iron (with a cloth over the lace) to smooth everything.
