Crossed Flat Stitch (Diagram 1):
Bring the needle up at A, move down over one canvas thread and to the right over three canvas threads, bring the needle down at B. Bring the needle up at C, move down over one canvas thread and to the left over three canvas threads, bring the needle down at D. Now continue on to Diagram 2...
Crossed Flat Stitch (Diagram 2):
Beginning where we left off at D, bring the needle up at E, move down over one canvas thread and to the right over four canvas threads, bring the needle down at F. Bring the needle up at G, move down over one canvas thread and to the left over four canvas threads, bring the needle down at H. As you can see from the diagram this part of the flat stitch is slightly longer than the first part. Now continue on to Diagram 3...

Crossed Flat Stitch (Diagram 3):
Beginning where we left off at H, bring the needle up at I, move down over one canvas thread and to the right over four canvas threads, bring the needle down at J. Bring the needle up at K, move down over one canvas thread and to the left over four canvas threads, bring the needle down at L. Bring the needle up at M, move down over one canvas thread and to the right over four canvas threads, bring the needle down at N. Bring the needle up at O, move down over one canvas thread and to the left over four canvas threads, bring the needle down at P. Bring the needle up at Q, move down over one canvas thread and to the right over four canvas threads, bring the needle down at R. Bring the needle up at S, move down over one canvas thread and to the left over four canvas threads, bring the needle down at T. Bring the needle up at U, move down over one canvas thread and to the right over three canvas threads, bring the needle down at V. Bring the needle up at W, move down over one canvas thread and to the left over three canvas threads, bring the needle down at X. Again, this last part of the stitch, like the first part, is slightly smaller than the rest. This helps create the "leaf" effect.
