It has finally happened!
I've been using valentina to draft #sewingPatterns for a while, using the upstream packages inside a virtual machine, and I can recommend it to other people who want to draft their own patterns from measurements (and not just because there are afaik no other free software alternatives).

I've been planning to try and package it for debian for a long time, but ended up spending my #sewing time on sewing-in-a-hurry instead of working on the tools, so I'm quite happy that somebody else had time to do it.
