Best Embroidery Thread for Machines (2026): 5 Kits and Cone Sets Compared

Last updated Researched from specs, manuals and owner reviews We earn from qualifying purchases
Quick answer

The best machine embroidery thread for most people is 40 wt polyester. Isacord is the premium standard, and the Isacord 35-cone set (about $190) gives 1,000 m per cone. On a budget, the New brothread 63-color kit (about $40) is matched to Brother color numbers and is plenty for a first machine.

For machine embroidery, 40 wt polyester is the thread to buy. It is strong, keeps its color through bleach and hot washes, and runs smoothly at speed. Our top pick is the Isacord 35 Cones at about $190: 35 best-selling colors on 1,000 m cones from a thread brand embroiderers widely trust.

You do not need premium thread to start. The New brothread 63-Color Kit (about $40) and Simthread 120 Colors (about $72) are popular with home embroiderers and cover a wide palette. The honest truth about thread is that your machine, needle and stabilizer matter more to stitch quality than the brand on the spool, which is why this page ends with the machines worth pairing it with.

Expert

Expert: brand-name thread for frequent stitchers, about $70 to $190

Premium thread earns its price when you stitch often, sell your work or run a multi-needle machine where cones last longer. If you embroider a few gifts a year, skip this tier; a budget kit will not hold you back.

What is the best thread for machine embroidery?

Polyester is the best all-round choice, rayon is the choice for maximum sheen on items that will not see bleach, and cotton is a specialty option for a matte, hand-stitched look. Metallic thread is for accents and needs a slower speed and a metallic needle.

What weight thread is used for machine embroidery?

Thread weight is a length-per-mass measure, so a higher number means a finer thread. Machine embroidery designs are digitized for 40 wt thread, which is what every kit on this page uses. A 30 wt thread covers faster but can look heavy on small details, while 60 wt is used for very small lettering and fine detail. Bobbin thread is usually lighter still, commonly 60 wt or 90 wt, so it stays hidden on the back. Our thread weight chart and thread weights guide convert between weight, tex and denier.

Can I use cotton thread in my embroidery machine?

You can, but it is rarely the best choice for machine embroidery. Cotton thread is weaker than polyester at high stitch speeds, sheds more lint into the bobbin area and can break on dense fill. Some quilters choose 50 wt cotton for a soft, matte look on quilt blocks, slowing the machine and using a fresh needle. Regular sewing thread, whether cotton or all-purpose polyester, is thicker and duller than embroidery thread and makes designs look coarse. For quilt piecing thread, see our best quilting thread page.

Why does my embroidery thread keep breaking?

Owner reviews for every thread brand mention breakage, and it is usually not the thread. Work through these in order.

Common causes of thread breaks and fixes
CauseWhat you noticeFix
Worn or wrong needleFraying, breaks after a few minutesFresh embroidery needle, commonly 75/11; see the needle size chart
Threading missed a guideBreaks at the start, loops on topRethread with the presser foot up

Old or dry threadSnaps easily, fuzzyReplace; store away from sunlight and heat
Spool catchingJerky feed, breaks at the spoolUse a spool cap or thread stand
Dense design at high speedBreaks in fill areasSlow the machine; check the design density

How do you match embroidery thread colors to your machine?

Designs list colors by a thread brand's numbers, and machines show a color name or number on screen. Kits that cross-reference those charts save guesswork: the New brothread 63-Color Kit maps to Brother numbers, the New brothread 150 Colors maps to Brother and Janome, and the Simthread 120 Colors matches Madeira shades. When a design uses a brand you do not own, pick the closest shade by eye in daylight. A wall rack like the Threadart 120 Spool Rack keeps a large palette visible and out of the dust.

How we chose

We did not test these threads in person. Picks are based on manufacturer and seller specifications (fiber, weight, length, color matching), current Amazon pricing, and recurring themes in verified owner reviews about breakage, sheen, lint and color accuracy. We prioritized 40 wt polyester because it suits the widest range of machines, designs and washing conditions.

Buying tips

  • Buy 40 wt polyester unless you have a specific reason not to.
  • Get bobbin thread separately; it is finer and cheaper than top thread.
  • Choose a kit matched to your machine brand's color numbers.
  • Move to cones once you stitch weekly or own a multi-needle machine.
  • Store thread away from sunlight, which fades and weakens it.
  • Hand embroidery uses stranded floss, not machine thread; see best embroidery floss.

Frequently asked questions

Is polyester or rayon embroidery thread better?

Polyester is better for most machine embroidery because it is stronger, holds color through bleach and hot washing, and breaks less at high speeds. Rayon has a softer, slightly richer sheen that some embroiderers prefer for heirloom and decorative pieces that will be washed gently. Trilobal polyester, like the Simthread 120-color kit, aims to combine polyester strength with a rayon-like shine.

What thread do you use in the bobbin for machine embroidery?

Use dedicated bobbin thread, which is finer than top thread, commonly 60 wt or 90 wt, and usually white or black. It keeps the back of the design flat and lets more bobbin fit on each wind. Some embroiderers use prewound bobbins for convenience. For designs where both sides show, such as freestanding lace, match the bobbin thread to the top thread instead.

Is Isacord thread worth the money?

For frequent stitchers, many embroiderers find it worthwhile. Isacord is a widely used polyester thread known for consistent quality, and the 1,000 m cones lower the cost per meter compared with small spools. If you embroider occasionally on a home machine, budget kits like New brothread or Simthread work well and let you build a larger color range for the same money.

How many thread colors do I need to start machine embroidery?

A 40 to 63 color kit covers most beginner projects, including monograms, names and built-in designs. Once you buy designs from shops with realistic shading, a 120 to 150 color palette avoids constant substitutions. Keep extra spools of black, white and your most-used colors, because those run out first, and add specialty threads such as metallic only when a project needs them.

Can you use embroidery thread for regular sewing?

It is not recommended for seams. Machine embroidery thread is designed to lie smoothly in decorative stitches and has a sheen that looks great on the surface, but it is not made to hold seams under stress the way all-purpose sewing thread is. Use it for topstitching accents and decorative stitches on a sewing machine if you like the look, and sewing thread for construction.

Does embroidery thread go bad?

Thread can weaken and fade over time, especially when stored in sunlight, heat or dry air. Old thread that snaps easily or looks fuzzy is a common cause of breaks. Polyester holds up better in storage than rayon or cotton. Keep spools covered or in a closed cabinet, and test an old spool by pulling a length firmly; if it snaps with little effort, replace it.
