Built for makers — improved with your feedback

Help shape Pattern Calculator

We are building Pattern Calculator for the people who actually use it. If something is missing, unclear or awkward — or you have an idea for a useful new tool — tell us. Good feedback can directly influence what we improve or build next.

A new tool or calculator

Tell us about a calculation or practical problem you regularly run into while knitting, crocheting, sewing, quilting or making something else.

Improve something that exists

Is an input, unit, explanation or project type missing? Did something feel confusing? Tell us what would make the current experience better.

Something else you noticed

Navigation, accessibility, translations, examples, layout and other ideas are welcome too. Small observations can be useful.

Leave feedback or an idea

You do not need to write a long proposal. A few clear sentences are enough. We read the feedback and use it when deciding what to improve. Where a reply is useful, we may also explain what we can or cannot change.

    Thank you for helping. We cannot promise that every suggestion will be built, but every useful comment helps us understand what real users need.
