About SkeinWise

Planning tools that show their work

SkeinWise helps crocheters turn their own project measurements into practical material estimates.

Why measured swatches

Generic blanket charts cannot know your yarn, hook, stitch pattern, or tension. Our calculator starts with a swatch you made and shows area scaling, uncertainty, buffer, and whole-skein rounding separately.

What we value

Useful tools should be understandable, private by default, and honest about limitations. SkeinWise presents a planning range, not a promise that one number will fit every handmade project.

Editorial approach

Examples and methods are written so you can check the calculation yourself. When a tool changes, its explanation and tests change with it.
