A more considered estimate

Useful numbers.
Clear boundaries.

Fabric behaves differently from one project to the next. Our goal is to help you plan, while making it easy to see what the estimate includes.

01

See each allowance

Seams, hems, selvage, pattern repeat, and waste should be visible parts of the estimate.

02

Keep your measurements private

Calculations are designed to happen in your browser. No account is needed to use the tools.

03

Use your judgement

These are planning estimates, not a professional cutting plan. Fabric, print, and technique all matter.
