Frequently Asked Questions

String art is a decorative craft where colored thread is wound between pins arranged in a pattern (often a circle) to create geometric designs. The thread forms straight lines between pins, but the envelope of these lines creates the illusion of curves — a beautiful demonstration of mathematical envelopes in geometry.

Multiplicative mode connects pin i to pin (i × step) mod n. This creates famous envelope curves like the cardioid (step=2) and nephroid (step=3). Additive mode connects pin i to pin (i + step) mod n, producing star polygons and cyclic patterns. Try both to see different geometric families!

Set the mode to Multiplicative, choose around 200 pins, and set the step to 2. You'll see the iconic heart-shaped cardioid curve emerge from straight lines! This is the same mathematical curve generated by the times-2 table on a circle — a classic visualization loved by math enthusiasts.

For physical string art, 24 to 72 pins is practical — too few and the pattern lacks detail; too many and hammering nails becomes tedious. Common choices: 36, 48, 60, or 72 pins. These numbers have many divisors, giving you more pattern options. Use this tool to preview before you build!

Our tool provides a thread length estimate below the canvas. Each chord length = 2 × R × sin(π × step / n). Multiply by the number of lines drawn. For physical projects, add 15-20% extra for wrapping around pins and knots. Using embroidery floss or crochet thread works great for most string art pieces.

In Additive mode, the number of independent loops equals gcd(n, step) — the greatest common divisor of pins and step. If gcd=1, all pins are connected in a single continuous path. If gcd>1, the pattern splits into that many separate cycles. This is a beautiful application of number theory in visual art!
