In this chapter, you did a lot of adjusting to fine-tune the shape of your hand. You learned how extra edge loops could be used to control rounding, shape large details such as muscles and tendons, and flatten the base of your piece. You learned how to select entire edge loops at once and how to slide them without distorting your shape. You learned how to correct a poorly positioned thumb by rotating vertices around the 3D Cursor. Finally, you learned about Blender's Proportional Editing tool and how it can adjust multiple items at once.
The 3D Printing Service Bureaus support full color printing. In Chapter 14, Coloring Models with Materials and UV Maps, you will learn how to take advantage of that by adding colors to your 3D model.
