Molding begins at which area of the oblong shape?

• A. Convex End
• B. Concave End
• C. Middle of the Shape
• D. Ridge

Answer: (A)

Molding begins at the convex end because that outward-curving edge establishes the outer boundary of the oblong shape. Starting there creates a solid baseline for the silhouette, so you can smoothly and evenly build the form as you move along the length toward the other end. If you try to start at the concave end, the inner curve is tighter and harder to control, which can lead to uneven transitions or pinches. The middle of the shape doesn’t provide a defining edge to anchor the contour, and a ridge refers to a high point rather than a starting boundary. By anchoring at the convex end, you set a natural flow for the rest of the molding and achieve a balanced, even result.
