Freyara is a bead-chart editor for a triangular peyote kaleidocycle: you colour 24 triangular faces bead by bead and export a PDF pattern booklet.
You want to plan the colours of a beaded kaleidocycle (a ring of six tetrahedra) before buying beads, and you are happy to test an experimental pattern with a small sample first.
Go to https://perunlight.com/apps/freyara/. The top toolbar holds the project name, Size, New, Open, Save, the examples (Control pattern, Sample) and the exports (PNG face, PNG sheet, Export PDF).
Click Sample for a small started design, Control pattern for the reference design, or New for an empty pattern. Under Size choose Compact - 6 beads per face edge or Large - 10 beads per face edge. Type a name in the Project box; exported files are named after it.
The Faces list shows all 24 faces in six groups (T1–T6) with the number of beads placed, for example 0/21. Click a face, choose Paint, pick a colour letter (A–H) and click or drag across the beads. Erase removes colour and Pick copies a bead's colour. Symmetry can paint 2, 3 or 6 matching beads at once.
Rotate 120°, Rotate 240°, Mirror, Fill face and Clear face change the current face. Under Repeat, Face → tetra, Tetra → ring and Rotate ring copy a design to other faces. Show Codes and Neighbours displays seam labels and joined faces. Add colour and the palette let you name your own colours.
Open Model, counts and validation details for bead counts per colour, seam “breaks” (places where colours will not line up across a seam) and the connector beads for hinges H1–H6.
Click Export PDF to download the pattern booklet with a bill of materials, colour legend, charts and assembly notes. PNG face saves the current face and PNG sheet saves all faces as PNG images. Click Save to download a .freyara.json project file; use Open to load it again.
Input: No file needed: Freyara's built-in Sample. To try re-opening a saved project, use examples/freyara/fictional-meadow-ring.freyara.json.
Expected: The status reads “Loaded the bundled sample project.” and face 1 shows 4 of 21 beads placed. Export PDF downloads fictional-meadow-ring.pdf, a 13-page booklet in our test. Save downloads fictional-meadow-ring.freyara.json with the message “Project file saved to your downloads.” Opening that file brings back the same pattern and name (“Opened fictional-meadow-ring.freyara.json.”).
That banner is part of this free preview. It marks the geometry as not yet validated. No key or purchase removes it, and it does not change the chart content.
Only one tab holds the shared autosave. Click Save to write a project file from the tab you are working in before closing it.
Two beads that meet at a seam have different colours. Click the seam under Joined faces to jump there and repaint, or keep it if the contrast is intentional.
Autosave only keeps recovery copies in this browser. Carry your work as a .freyara.json file made with Save.
