This is the important step in the long and short stitch. We are going to fill up the second row using one strand of thread. In the basic long and short embroidery, the second row of stitches start at the points where the first row stitches end. However to get a smooth blending effect, we should bring up the needle through the first row of stitches by spliting up the thread of the first row of stitches, not at the endpoints of the stitches in the previous row. Look at the image below:
Because the petal is small, I decided to limit the long and short stitch to only two rows. Since the second row is also the last row, the stitches should be directed toward and end at the inner edge of the petal.
Continue to place the stitches close to each other as you did for first row.
