Got annoyed using a ruler as wraps per inch gauge, looked around for a model, and not a single one includes metric units! Also many have these American yarn categories written, like Fingering/Sport, that mean nothing here and not much for #weaving anyway. So I've designed (in #FreeCAD, of course) and printed this unit systems inclusive #wpiGauge, so much better than using a ruler!
