Closed buttonhole stitch is a variation of buttonhole stitch. It is easily worked and can be used as an edging or worked in multiple rows to create a patterned border or fill in an area.
Work closed buttonhole stitch from left to right over two parallel guide lines which are first marked on the fabric using a water dissolvable marker or fade out fabric marker.
Bring the thread out on the lower line, insert the needle slightly to the right on the upper line and make a downward diagonal motion, with the needle pointing left, bringing the needle point out on the bottom line.
With the thread looped the needle point, pull the needle through the fabric.
Insert the needle on the top line close to the top of the stitch you just created. Make a downward diagonal motion, with the needle pointing right, bringing the needle point out on the bottom line. Continue this process sewing along the line.
Since Closed buttonhole stitch has a strong geometrical construction. It lends itself to building up in rows in order to create patterns. Rows of Closed buttonhole worked closely together produce a net effect, which makes a good filling for larger areas. Since this creates a grid of shapes an isolated stitch such as French knot or a bead can be placed in the centre to further decorate the filling. Closed buttonhole is also a useful decorative stitch to use when couching and can be an interesting and different seam embellishment in crazy quilting.
