Step one:
Draw an arc first.
Step 2:
Then use small polylines to draw the feeling of leaves.
The third step:
Draw a small circle in the middle and draw several lines to the tip of the leaf to form veins.
Step 4:
Then draw two long ovals below.
Step 5:
Use small polylines under the oval to draw the shape of the flower.
Step 6:
A vertical stripe texture should be drawn inside the oval.
Step 7:
Then use curves and arcs to draw the filaments of the loofah.
Step 8:
Finally, apply a nice color and the loofah is finished.
