# Making thread portraits with the String Art Generator

> a photo redrawn as thread stretched between pegs

String art turns a portrait into thousands of straight chords: a single dark thread zig-zags between pegs around a ring, and where the chords pile up, the image darkens. This tool solves the hard part, computing which peg to visit next, and gives you everything physical: an SVG peg ring for the laser, a numbered thread sequence as a text file, plus faux options that score or print the finished thread pattern directly onto a panel.

Choose your adventure: thread the real thing for a meditative heirloom, or let the laser score the computed pattern in minutes for the look without the labour. Processing is local; your photo never uploads.

## What you need

- **Real string art (laser):** laser cutter, 3 mm [laser-grade plywood](https://yxecreations.com/collections/laser-grade-plywood) for the peg ring, a spool of dark sewing thread or fine crochet cotton
- **Faux scored version (laser):** laser cutter and a light-toned panel, plywood or pale [acrylic](https://yxecreations.com/pages/acrylic-sheets)
- **Printed version:** any printer (or a print shop for large formats) and a frame

## Step 1 - Upload and adjust



Open the tool and upload a photo; high-contrast portraits on plain backgrounds convert best. Shape the tones with **Gamma**, **Brightness**, and **Contrast**; string art only renders darkness, so push the midtones until the subject dominates the preview.

## Step 2 - Tune the threading



- **Ring Diameter** (150 to 600 mm) sets the physical size; bigger rings resolve more facial detail.
- **Number of Pegs** controls angular resolution; around 200 to 300 suits portraits.
- **Thread Count** is how many chords get drawn; watch the preview build and stop where the likeness peaks before shadows clog.
- **Thread Darkness** models how much each pass darkens, tuning the simulation to your actual thread.
- **Min Peg Separation** forbids short hops along the rim that waste thread on the edge.
- **Thread Colour** sets the export color for the faux versions.

## Step 3 - Export



Four downloads cover every route: the **peg ring SVG** (cut file with numbered peg positions), the **thread sequence TXT** (the peg-by-peg instructions), the **thread SVG** (every chord as vector lines for scoring), and a high-res **PNG** of the simulated result for printing.

## Laser: Real & Faux String Art

### Real thread on a laser-cut ring



1. Cut the peg ring SVG from 3 mm plywood; the file includes the peg holes and numbering.
2. Fit the pegs (cocktail sticks, brads, or laser-cut pins) and anchor the thread at peg zero.
3. Open the sequence TXT and follow it peg by peg; a highlighter and an hour-long playlist are the real tools here.
4. Keep tension light and even; the image emerges in the final third of the sequence.
5. Tie off, dab the knot with glue, and frame in a shadow box.

For the faux version, import the thread SVG instead and score every chord onto a light panel at low power; the laser draws the full pattern in minutes and the result reads as ink-drawn string art. Cut the ring outline in the same job.

## Printing

### Printing the pattern



1. Download the PNG; it renders the simulated threads at print resolution in your chosen Thread Colour.
2. Print at home up to A3, or send to a poster printer for statement sizes.
3. Matte paper sells the hand-threaded illusion better than gloss.
4. A UV-printable panel takes the same PNG straight onto wood or acrylic for a gallery-ready piece.
5. Frame behind glass with a deep mat so viewers lean in to check whether it is real thread.

## Make it yours

- Thread a wedding portrait as a first-anniversary (cotton) gift, sequence file included in the card.
- Pet portrait in the faux scored style for a one-evening memorial piece.
- Kit gift: cut the ring, coil the thread, print the sequence, and let them thread their own.
- White thread on black panel: set Thread Colour light and print on dark stock.
- Score the chords and engrave a name plate into the same panel in one job.
- Giant 600 mm ring above the fireplace, threaded over a family movie marathon.
- Heart-photo string art for Valentine's using a tight square crop.
- Print a mini version as the card that accompanies the real threaded gift.
