Lee,
I would hand sketch applique by hand & stick to solids or non-distracting fabrics for the applique...I might even consider hand dyed for that brown to get some variation in color. Additionally, I would ask for my client's approval for the final sketch and explain each of the pieces required and the hours already spent on the design.
In the approval meeting, I would also provide a small sample of a simple design with an explanation of how long the simple version took so they understand the amount of time required for this project. If you have difficulty drawing realistically by hand, I may have someone I can refer for assistance.
Best of luck,
Heather
