Tally & Make and the Yarn Calculator That Starts With Your Swatch

Field notes

The live calculator covers jumpers, cardigans, hats, and scarves, and bases its estimate on a maker’s tension swatch and intended fit. The project is organized as a sequence of one-question calculators rather than a single large application. Its creator says future additions will arrive roughly every few weeks and that user votes will help decide what gets built, while acknowledging that some experiments may be dropped.
