Analyzing the Question

This question asks for a tool that serves two purposes: general marking and measuring fabric grainline when laying out a sewing pattern.

Evaluating the Options

1. Ruler: A straight tool primarily used for measuring length. It's useful for marking straight lines but not specific to fabric grainline.

2. Sewing Gauge: A small tool that features a sliding marker, typically used for measuring hems, seam allowances, and other small distances in sewing. This could be used for marking and measuring but is not primarily for larger layouts.

3. Tape Measure: A flexible measuring tool that is commonly used in sewing for measuring distances, fabric lengths, and other dimensions. It can be used for marking but may not be as precise for laying out patterns.

4. Yard Stick: A rigid stick typically used for measuring longer distances (up to a yard). Similar to a ruler but longer.

Conclusion

The most suitable option for both general marking and measuring fabric grainline when laying out a pattern is B. Sewing Gauge due to its versatility for small measurements in fabric layout and specific sewing tasks.

Final Answer

B. Sewing Gauge
