How does the tool handle seam allowances?

The tool automatically adds a 1/2 inch seam allowance to standard pieces and a 7/8 inch allowance for half-square triangle components to ensure accuracy.

Can I calculate yardage for on-point quilt settings?

Yes, by using `calculate_quilt_layout` with the `isOnPoint` parameter set to true, the tool calculates the correct dimensions and subsequent fabric needs.

What fabric width should I use?

You can specify your fabric's usable width (typically 42 or 44 inches) in the `calculate_fabric_requirements` tool to get accurate yardage results.
