Double corded Brussels stitch
Double corded Brussels stitch is a needlelace stitch consisting of detached butthonhole stitches worked over a pre-existing outline. This is a more open filling stitch than single corded Brussels stitch, so the gap between the two double buttonhole stitches should be made a little wider.
Double Corded Brussels stitch is attached to the background of the fabric only at the edges of the shape. In the example below, a simple back stich outline is used, but this could be a cordonnet when making a needlelace slip.
For more background see the entry for single corded Brussels stitch.
Work two buttonhole stitches at the top left-hand corner of the shape and leave a gap between the two double buttonhole stitches as for double Brussels stitch.
Pull the thread through to form a cord going across the shape as you do in single corded Brussels stitch. Whip down the left-hand side edge to bring the needle just below the cord.
Work another row of double buttonhole stitches from left to right, passing the needle through the loops between the two double buttonhole stitches of the previous row and the cord.
Form a cord again and continue to work rows of double buttonhole stitches until you fill the shape. On the final row, pass the needle through the loop, the cord and the bottom outer edge.
