Scotch Stitch - Horizontal Method (Diagram 1):
In order to make this demonstration easier to follow, the first stitch is shown in light blue and the second stitch is shown in dark blue. Bring the needle up at A, move up and to the right over one canvas intersection, bring the needle down at B. Bring the needle up at C, move up and to the right over two canvas intersections, bring the needle down at D. Bring the needle up at E, move up and to the right over three canvas intersections, bring the needle down at F. Bring the needle up at G, move up and to the right over two canvas intersections, bring the needle down at H. Bring the needle up at I, move up and to the right over one canvas intersection, bring the needle down at J. This completes the first Scotch Stitch.
Now, bring the needle up at K, move up and to the right over one canvas intersection, bring the needle down at G. Bring the needle up at L, move up and to the right over two canvas intersections, bring the needle down at I. Bring the needle up at M, move up and to the right over three  canvas intersections, bring the needle down at N. Bring the needle up at O, move up and to the right over two canvas intersections, bring the needle down at P. Bring the needle up at Q, move up and to the right over one canvas intersection, bring the needle down at R. Continue working in this manner until the end of the row. At the end of the row, turn the canvas around and work the next row into the first row. Diagram 2 illustrates how this stitch should look when complete.
