Use Standard Backstitch 
to outline traditional cross stitch designs or to create blackwork. Standard Backstitch places lines along the sides of grid squares or diagonally across grid squares. Standard Backstitch is stitched out after the crosses.
Use single-click to place or erase individual lines of Standard Backstitch, or drag to draw connected Standard Backstitch lines.
Only standard backstitch can be placed or erased when Standard Backstitch is selected. Crosses, freehand backstitch and French knots are unaffected.
Note: Two diagonal Standard Backstitch lines can produce an effect similar to a Full Cross. It is recommended to avoid placing this in the same square as a Full Cross, because the backstitch will stitch on top of the cross and hide it.
