The arrowhead stitch (also sometimes known as an arrowhead) is a diagonal form of stitching, in which a zig-zag effect is created. There are various different ways to create an arrowhead stitch. In the particular example drawn here, the needle comes out at A and goes back into the ground cloth at B. It then resurfaces at C and goes back through the ground cloth at D and so forth.
