Begin by working a diagonal row of interlocking square stitches. Make a tent stitch across one intersection of the canvas,
then below it make stitches across two, three, four, three, two then one intersection again.
Once this row is complete make the smaller square stitches in the spaces. These begin with a reversed tent stitch, then a stitch across two,
Repeat these along the row. The longest of the stitches should touch at the corners.
