Bring the needle up at D, move to the right over two canvas threads, bring the needle down at C. Bring the needle up at E, move down and to the right  over one canvas intersection, bring the needle down at D. Bring the needle up at F, move down and to the left  over one canvas intersection, bring the needle down at E. Bring the needle up at G, move to the left over two canvas threads, bring the needle down at F. Bring the needle up at H, move to the left over two canvas threads, bring the needle down at G.
