Pattern checker

Paste any amigurumi pattern to check every stitch count, design a single shape and get its pattern, or open a ready-made toy. The 3D model is drawn from the stitch counts alone, so what you see is what the pattern makes.

How it works

Design: your shape is traced as an outline. Every round adds one stitch of height along that outline, and the stitch count is the ring's circumference divided by one stitch width. Counts never change faster than the fabric can curve.

Math: each round's steps must add up to the count it claims, and must use exactly the stitches the round before made.

Shape: each round is treated as a ring. More stitches make a wider ring, and each round adds one stitch of height. If a round grows or shrinks faster than one stitch-height allows, the fabric can't curve smoothly, so it ruffles or bunches.

Not simulated yet: stuffing, sewing parts together, and yarn stretch. Sizes are before stuffing.
