- •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 Travel With the File
XXX embeds an RGB colour table, so the thread colours you set in SewFlow are saved inside the file and show up in your Singer software.
