How the calculation works
Each supported instruction has a consumed count and a created count. The checker compares consumption with the previous computed round, and production with the written total. It does not alter your text or guess unknown instructions.
Worked example
(4 sc, inc) x 6 consumes 30 stitches and creates 36. If the written total is [35], that line needs review. An unknown instruction stops the starting-count chain until another magic-ring start.
What this tool covers
US single-crochet notation only: sc, inc, dec/sc2tog, comma-separated instructions, simple parenthesized or starred repeats followed by x and a number, sc in each stitch around, inc around, dec around, and magic-ring starts. Totals may be [36] or (36 sts). No nested repeats, UK dc, chains, joins, color instructions or special stitches. At most 200 lines and 50,000 characters. Count agreement does not validate shape, assembly or safety.
Inputs stay in this tab. “Use in a creation” prepares a result for your review in the studio. It does not change an existing creation until you choose Apply.
