Important: This calculator is provided "as is" for informational purposes. While we strive for accuracy:

Limitation of Liability

We are not liable for any damages arising from the use or inability to use this service, including but not limited to material waste, project failure, property damage, or personal injury while crafting.

Accuracy

We make every effort to ensure calculations are accurate, but costume material needs can vary due to manufacturing tolerances, fabric nap, and other factors. Always measure your actual project components when precision is critical.

We may update these terms at any time. Continued use of the service after changes constitutes acceptance of the updated terms.
