We will see steps 3 and 4 today.
Step 3: Now, with everything set, you are ready to start the embroidery. With two strands of the darkest shade of pink sew buttonhole stitch around the edges of the flower pattern. Buttonhole stitch is used here to avoid frayed edges when the flower is cut out from the fabric. Place the buttonhole stitches very close together.
Step 4: Before you start the shading, observe the flower and find the order of working the flower. When you shade the flower, first shade the petal which is underneath all the other petals. Marked as A in the photo below. Next, petals marked as B, and then petal C. And at last, petal D, which is on top of all the other petals.
