Everyone talks about the embroidery file, but the final result depends just as much on thread. Here's what matters when choosing: fiber, shades, and the tricky question of matching file colors to your thread rack.
Polyester or rayon (viscose)?
- Polyester (Madeira Polyneon, Isacord, Gutermann Mara…): very resistant to washing, chlorine and wear. The default choice for professional textiles (polos, uniforms, linens).
- Rayon/viscose (Madeira Rayon…): superior sheen, silky look ideal for decoration and display pieces. Less resistant to harsh washing.
- Cotton: matte, authentic look, but more fragile with fewer shades — mostly for art embroidery.
Simple rule: anything washed often goes in polyester; anything on display (decor, framed) can shine in rayon.
Shade charts and color matching
The big brands — Madeira, Isacord (Amann), Gutermann, Brother — each offer 350+ shades plus conversion tables between them. Serious software and converters map each color area of the design to a shade reference: that's what lets you order (or pick from your stock) the exact thread the file expects.
Brode can align the design's colors to the Madeira Polyneon shade chart (about 350 polyester references) and passes those colors to formats that carry them — exact in VP3 and XXX, nearest machine thread in PES and JEF: the machine then displays the expected shade, and you know which thread to load at each change.
Tips for a crisp result
- Stay consistent: don't mix rayon and polyester in one design — the sheen difference is obvious.
- Bobbin thread: same fiber or fine polyester bobbin thread; a badly tensioned bobbin ruins fill-stitch regularity.
- Match density to thread: metallic threads are stiffer and can't handle high density — reduce by 10–15%.
- Test colors on the final fabric: the same green can look muted on light fleece and electric on black cotton.
Once your threads are chosen, everything starts with a good conversion: a file with cleanly separated color areas gives you one thread change per area, no surprises. So these areas stitch cleanly (underlay, satin, tatami) — that's exactly what Brode does during image preparation.
