Make a horizontal stitch across four canvas threads.

then make a vertical stitch of the same length across the middle of it.

Next, make a diagonal stitch across the centre of this cross, covering two canvas intersections from bottom left to top right.

Finally, make another diagonal stitch of the same length from bottom left to top right.

Work the crosses in horizontal rows. The next stitch to the right should join at the left-hand edge of the previous cross.

The next row is worked below the first, two canvas threads down and across, so that the crosses fit into the gaps of the previous row. Make sure the top stitch on all the crosses always lay bottom left to top right.
