Crochet Symbol Studio
Place crochet symbols into alternating rows or outward-facing circular rounds, then edit the chart and its counting assumptions. Real vector downloads include a symbol key and count report. Your work stays in the browser, with an editable JSON project you can save and reopen.
How we build a check
This workbench processes supported inputs locally. We test calculations, file structure and generated artifacts using independent readers or known fixtures where available. The example runs the same processing path as a supplied input; it does not stand in for checking your own result.
