Get in touch

I read everything and aim to reply within a few days. Useful things to write about:

Corrections — a wrong number, a broken link, a source that moved. These go to the top of the queue.
Calculator requests — what math would you like automated next?
Cheat sheet requests — printable tables you keep re-Googling.
Source disputes — if you have a better or newer published standard for something, send the link.

Please note I can't provide personal project consultations (sizing advice for your specific sweater, pattern support for another designer's pattern) — the calculators and guides are the full toolkit I can offer.
