Explaining brush sizes
Step 1: Brush sizes are numbered, with smaller numbers indicating smaller, finer brushes suitable for detailed work, and larger numbers indicating thicker brushes for broader strokes.
Considering the task
Step 2: Drawing the outer lines of a flower requires precision and fine lines, best achieved with a smaller brush like No. 2.
Evaluating options
Step 3: Analyze the options:
- (A) No. 2: A fine brush, ideal for detailed outlines.
- (B) No. 4: Slightly larger, less precise for fine outlines.
- (C) No. 6: Larger, better for filling or broader strokes.
- (D) No. 7: Larger still, unsuitable for fine outlines.
Thus, the correct answer is (A).
