Best Embroidery Thread for Stitching – Our Picks

The great thread war comes down to two camps: polyester and cotton. Polyester threads (like SIMTHREAD or NEW BROTHREAD) are the workhorses-they’re strong, colorfast, and won’t shrink or bleed in the wash. They have a glossy sheen that makes machine embroidery pop. But they can feel a bit plasticky to hand sewists. Cotton floss (like LOVIMAG or LE PAON) is softer, more natural, and has a matte finish that’s ideal for hand stitching and cross stitch. It’s lovely to hold, but it can fray and fade faster. If you’re heavy into machine work, polyester wins. If you’re all about the hand feel and vintage aesthetic, go cotton.

Thread weight is like the spice in a recipe-too much or too little, and you ruin the dish. The most common weight for machine embroidery is 40WT, and all the machine threads in our list hit that sweet spot. It’s thick enough to cover in a few passes but fine enough not to jam your needle. Hand embroidery floss is usually labeled as 6‑strand, meaning you separate it to the thickness you want. Use all strands for bold lines, or just one for delicate details. Whatever you do, match your needle size to your thread; a too-thick thread in a too-small needle spells disaster.

Not all color sets are created equal. A 140‑color kit might seem like a clear winner, but if half of them are shades of brown you’ll never use, you’ve wasted money. Look for balanced palettes with good representation of primary and skin tones. The SIMTHREAD 120 kit, for example, includes variegated options that add dimension without extra work. Conversion charts are a hidden superpower-if you follow patterns from specific brands like Brother or Madeira, a compatible thread set saves you from guessing and color mishaps.

You spend hours on a project; the last thing you want is for the colors to bleed into a muddy mess after one wash. Polyester threads generally excel here-they hold fast against bleach, sweat, and hot water. Cotton floss can be more temperamental, though double‑mercerized cotton (like LE PAON) is specially treated to resist fading. Always check care instructions, and if in doubt, do a quick rinse test on a scrap fabric. Nothing’s worse than opening the washer to find your white shirt turned pink.

If you’re using an embroidery machine, this is non-negotiable. Some threads are specifically engineered for certain brands. The NEW BROTHREAD kit, for instance, matches Brother’s color codes perfectly, reducing tension issues. While most polyester threads will work in any machine, you may need to tweak tension settings. Always read your machine’s manual-some machines are picky eaters. Hand stitch? You’re off the hook; use whatever feels right.

A messy thread stash can kill your creative momentum. Look for sets that come with built‑in organization, like the SIMTHREAD 80 box, or at least provide spool numbers. Color‑coded tags and charts that fit on a ring binder are small features that save you hours of hunting. Your future self will thank you when you’re not detangling a pile of floss at midnight.

Friendship bracelets, machine embroidery on denim, delicate heirloom cross stitch-each demands something different. For bracelets, cheap polyester floss is fine; it’s meant to be handled. For garments, prioritize colorfastness. For display pieces, sheen matters more than strength. Think about how the thread will be seen and touched. Sometimes a tiny investment in the right thread elevates a project from “meh” to “where did you buy that?”
