    Both make beautiful embroidery, but they differ in sheen, strength, and colorfastness. This guide walks through the technique step by step, with practical tips to get clean results — and shows where a free tool like SewFlow fits in.

    Step by Step

    1. 1Choose polyester for items that get washed often or bleached.
    2. 2Choose rayon for a softer sheen on decorative pieces.
    3. 3Use polyester for kids' and work garments for durability.
    4. 4Match thread weight (usually 40wt) regardless of fiber.

    Tips for Best Results

    • Polyester resists fading and bleach better than rayon.
    • Rayon has a slightly softer, more natural shine.
    • Polyester is the safer all-around choice for apparel.

    Durable vs. Soft Shine

    Polyester wins on durability and bleach resistance; rayon edges ahead on softness and sheen.
