SEW is an older stitch format from the Janome family, read by some Elna and Bernina machines too. With SewFlow you can turn a flat PNG into a machine-ready SEW file in seconds — no digitizing software required.

- •Use bold, flat artwork — embroidery cannot reproduce photographic gradients.
- •Keep small designs above 30 mm so fine detail survives in thread.
- •Limit the palette to a handful of solid colours to reduce thread changes.
- •Always test stitch on scrap fabric before committing to your final garment.
Colours Match the Janome Chart
SEW references Janome's thread chart, so SewFlow maps each colour you choose to the nearest chart entry — check the colour order at your machine.
