Terms of use

By using StitchMath you agree to these terms. If you do not agree, please do not use the site.

Guidance, not guarantees

Our calculators and guides are educational estimates. Leather is a natural material and tool specifications vary between makers, so always double-check measurements and suitability before cutting or buying. We are not liable for material wasted, tools bought, or injuries sustained while working — you are responsible for your own safety and for following tool and chemical manufacturers’ instructions.

No professional advice

Nothing here is professional, legal, medical or safety advice. We make no “food-safe”, “hypoallergenic” or similar claims about any leather or finish.

Third-party links

We link to third-party retailers and resources we do not control and are not responsible for their content, prices or availability.

Changes

We may update the site and these terms at any time. Continued use means you accept the current version.
