A motif you can edit.
A chart you can read.
Draw colourwork, see the PDF page plan beside your chart, then take away a chart and colour legend. Keep the editable project for the next revision.
Open a folder. Start drawing.
- Extract the complete buyer ZIP. Open
app/frigella-standalone.htmlwith desktop Google Chrome. - Choose Chevron repeat in Load a sample chart. No input file or account is needed.
- Read the size and page plan above the chart. Click Download PDF. The default sample has one chart page and one legend page.

Make the motif yours
Choose a palette colour, then paint cells with Pencil. Keyboard users can Tab to Skip to chart, press Enter, choose a palette colour with 1–9 or 0, move with the arrow keys and paint with Enter. Undo restores an edit.
New starts a blank chart. Set Width and Height under Chart size, choose the retained corner and click Apply size. Both dimensions range from 1 to 200. Select an area to mirror or repeat it. Rotate 90° requires a square selection. Save an editable copy before a major change.

Know what will come out before you download
PDF settings opens the existing page controls. The plan updates when you change them. For the Chevron sample, choose Fixed cell size and Cell height 30 pt: the result becomes two chart pages plus one legend page. Switch back to Fit the chart on one page for the default two-page output.

For a black-and-white chart, keep Print symbols in the cells enabled. Turning it off can produce blank cells; the page-plan warning tells you before export. At very small cell sizes, symbols can also be suppressed. Read the warning and adjust your page settings.

Keep an editable project, not just the PDF
Use Save or Save as... for a .frigella.json file, and Open... to restore it. Chrome can show a native file dialog; browsers where that API is unavailable use a download and regular file chooser. Cancelling a dialog does not save. Browser recovery storage is not a backup.
The editable Chevron example has the same 240 cells and two colours as the default PDF. A malformed or unsupported project shows an error while preserving the current chart. A successful New, sample load or Open clears the stale error.

Scope and troubleshooting
| What you see | What to do |
|---|---|
| Save cancelled | Choose Save as... again and finish the dialog. Look for the file before closing the app. |
| Rotate is unavailable | Select a square region before rotating 90°. |
| Blank cells in a monochrome PDF | Enable cell symbols and choose a cell size large enough to print them. |
| Licence / development issuer message | The local features need no activation key. The existing issuer is unconfigured, and the panel says so. The purchase supplies this local package, guide and examples; no separate Pro activation or hosted account is promised. |
| The page feels crowded on a phone | Use desktop Chrome for editing. Narrow layouts were checked for reflow, not full phone or physical touch usability. |
Verified with Chrome 152 on Linux, offline. Native OS file dialogs, other browsers and operating systems, physical printers, iPad PWA installation and knitted samples remain unverified. Save/Open automation used the existing browser download/file-input fallback; it did not validate native OS picker interaction. The app keeps the original 200 × 200 chart limit and existing licence behavior.
