Sewing joins pieces of fabric into a product; embroidery decorates a piece of fabric that already exists. That one difference drives everything else on the production floor. Sewing needs strong, abrasion-resistant spun thread, such as 40S/2 polyester, and seam stitches like lockstitch and overlock. Embroidery needs smooth, high-sheen filament thread, usually 120D/2 polyester or viscose rayon, and decorative stitches like satin and fill.
Key Takeaways
Sewing = construction (seams, hems, joins). Embroidery = decoration (logos, motifs, monograms) on fabric that’s already cut or sewn.
Sewing thread is usually spun or core-spun polyester (20S/2 to 60S/3); machine embroidery thread is usually filament polyester or rayon around 120D/2.
Embroidery thread isn’t built to hold a seam, and sewing thread lacks the sheen and smooth flow embroidery heads need.
Hand embroidery and cross-stitch use 6-strand cotton floss and counted fabrics such as Aida cloth.
What Are the Key Differences Between Sewing and Embroidery?
The difference is purpose. Sewing joins two or more layers of fabric to make functional items such as garments, bags, cushions, curtains, quilts, and other household products, and it is also used to repair or alter existing pieces so they keep their shape under wear and washing. Embroidery serves different purposes: it is non-structural surface embellishment, building a design out of thread on one fabric layer for decorative purposes rather than holding the product together. A shirt can be sewn without embroidery, but the embroidered logo on its chest still needs the shirt to be sewn first, or at least the front panel to be cut.
That is why the two usually sit in different departments, or even different factories: they are separate textile processes with different purposes, materials, and workflow requirements. Sewing happens on the line, piece by piece. Embroidery often happens on cut panels before assembly, or on finished garments in a separate decoration step. For garment manufacturers, embroidery workshops, uniform makers, craft-kit brands, and other textile producers, the distinction affects product durability, appearance, care performance, and thread choice. The comparison below looks at sewing vs embroidery in practical terms, including thread types, uses in garment production, selection guidance, and MH's sewing and embroidery thread products.
Factor | Sewing | Embroidery |
|---|---|---|
Purpose | Joins fabric pieces into a product | Adds a design to the fabric surface |
Typical thread | Spun polyester, core-spun poly/poly or cotton/poly, cotton | Filament polyester, viscose rayon, metallic; cotton floss by hand |
Thread priority | Tensile strength, abrasion resistance, low breakage | Luster, color range, smooth running at high speed |
Common sizes | 20S/2 to 60S/3 (heavier for denim and bags) | 120D/2 standard; 75D/2 for fine detail; 150D-300D for bold fills |
Key stitches | Lockstitch, chainstitch, overlock, coverstitch | Satin, fill (tatami), running stitch; cross-stitch and French knot by hand |
Machines | Industrial lockstitch, overlockers, coverstitch machines | Single- or multi-head embroidery machines reading digitized files |
Extra materials | Interlining, tapes, zippers, buttons | Backing (stabilizer), bobbin thread, topping for pile fabrics |
How it’s costed | Labor minutes per garment | Mostly by stitch count and number of colors |

What Is Sewing?
Sewing uses a needle and thread to join pieces of fabric with a seam. In garment production that means seams, hems, darts, topstitching and attaching trims, with sewing thread also used for construction, darning, and serging. Every seam has to stretch, flex and survive laundering without breaking, so sewing thread is chosen for strength first and looks second.
For beginners, various techniques often start with simple methods such as running stitches and backstitch.
Fabric drives the choice. Sewing is also a versatile skill with practical applications beyond garment production. Cotton shirting and denim, knits and stretch fabrics, upholstery and bags each call for different fabric and thread pairings. A light knit seam needs a finer thread with some stretch; a jeans seam needs a heavy 20S/3 or core-spun thread.
What Is Embroidery?
Embroidery decorates fabric with thread, building a design from thousands of closely placed stitches. It doesn't join fabric pieces. Instead, embroidering is about decorating fabric for decorative purposes and creating visually appealing designs rather than construction. It sits on top of the fabric and changes how the surface looks: a brand logo on a polo, a monogram on a towel, a floral border on a dress.
Most commercial embroidery is done by machine, with designs converted ("digitized") into stitch files. Hand embroidery survives in craft kits, couture and decorative home textiles, where beginners often start with simple patterns, though embroidery may be more challenging than sewing because it requires more precision. Fabric is usually held taut in an embroidery hoop or frame, and common tools include hoops, needles, and embroidery floss. Either way, the color and shine come from the embroidery threads, which is why thread choice matters so much more for looks here than in sewing, especially when outlining and filling in intricate designs with colorful threads.
Sewing Thread vs Embroidery Thread: What Changes?
Sewing thread is built for strength, while embroidery thread is built for sheen and smooth flow, a clear contrast between regular sewing thread for construction and decorative thread for surface detail. Spun polyester sewing thread is made from short staple fibers twisted together, which gives it grip in the seam and good abrasion resistance. Embroidery thread is made from long continuous filaments, which lie flat, reflect light and run smoothly through a needle at high speed.
Sewing uses regular thread in different weights depending on the job, and common options include cotton, polyester, and nylon.
Thread | Construction | Typical sizes | Best for |
|---|---|---|---|
Spun polyester sewing thread | Staple fibers, 2 or 3 ply | 20S/2 to 80S/2 | General garment seams, knits, home textiles |
Core-spun sewing thread | Polyester filament core wrapped in polyester or cotton | 20S/2 to 45S/2 | Jeans, sportswear, outerwear, leather goods |
Cotton sewing thread | 100% cotton, often mercerized | Varies | Garment-dyed items, natural-fiber products |
Polyester embroidery thread | Continuous polyester filament | 75D/2 to 300D/3 | Workwear, kidswear, uniforms, items washed hard |
Viscose rayon embroidery thread | Continuous viscose filament | 120D/2 to 600D/3 | Fashion, lace, ladieswear, high-luster logos |
Cotton embroidery floss | 6 divisible strands, mercerized cotton | 32S/2×6 | Hand embroidery, cross-stitch kits |
Size ranges from MH polyester, core-spun, embroidery and floss thread pages.
Polyester or rayon for embroidery? Rayon gives the softest hand and the highest luster, though decorative options also include silk and specialty threads. Polyester holds its color better through bleach and industrial laundering, so it's the safer pick for workwear, hospitality linens and children's clothing. MH's rayon embroidery thread and spun polyester sewing thread are both OEKO-TEX® certified for skin-contact products.
Where Are Sewing and Embroidery Used in Production?
Sewing creates clothes, home decor, and other fabric items by joining pieces with seams; embroidery decorates those same fabric items with branding, identity or decoration. In practice most finished goods use both, at different stages.
Product | Sewing does | Embroidery does |
|---|---|---|
Corporate polos and uniforms | Body seams, collar, placket, hems | Company logo, name badges |
Workwear and hi-vis | Heavy seams with core-spun or high-tenacity thread | Logo that must survive industrial washing (polyester thread) |
Caps and bags | Panels, straps, linings | 3D or flat logos on front panels |
Fashion and ladieswear | Construction seams | High-luster rayon motifs, lace, borders |
Towels and home textiles | Hems and binding for home decor pieces | Monograms, hotel branding, decorative borders |
Craft and DIY kits | Usually none | Hand embroidery on Aida with cotton floss |
Beginners often start sewing with small projects like cushions, and those usually take less time than embroidery projects.
Embroidery has a long history as an art form across different cultures, with regional styles that tell stories through motif and color; in medieval Europe it could also signal status. In modern supply chains it's mostly about branding: a logo that stays sharp through dozens of washes. Sewing, meanwhile, is about the product lasting at all, while embroidery can preserve cultural traditions and add aesthetic appeal.
Sewing or Embroidery: Which Thread Does Your Order Need?
Most garment orders need both sewing and embroidery thread families because both sewing and embroidery use needle and thread, but for different purposes. Ask what the thread has to do. If it holds fabric together, choose a sewing thread by fabric weight and end use. If it shows on the surface as a design, choose an embroidery thread by look and care conditions.
Seams on woven garments and home textiles: spun polyester sewing thread such as 40S/2 or 50S/3 for garment construction; hemming also helps prevent fabric edges from fraying and gives a clean finish.
Denim, bags, leather and outerwear: heavier 20S/2-20S/3 polyester or core-spun thread.
Logos on workwear, uniforms and kidswear: polyester embroidery thread, 120D/2.
Fashion embroidery, lace and premium labels: viscose rayon embroidery thread for maximum shine.
Cross-stitch and hand-embroidery kits: cotton floss plus Aida cloth.
A basic sewing kit includes threads, needles, scissors, and a measuring tape. Standard sewing machines use feed dogs to guide fabric, and the right tools make projects easier.
Color matching works differently too. Sewing thread is matched to the fabric because sewing focuses on joining pieces of fabric together, while embroidery brings embellishments so the design stands out.

Sewing and Embroidery Threads from MH: Both Sides of the Spool
MH (Ningbo MH) makes both families in its own thread factory: polyester sewing thread from 20S/2 to 80S/2 in 800+ colors, core-spun thread for denim and outerwear, polyester embroidery thread from 75D/2 to 300D/3, and viscose rayon embroidery thread up to 600D/3. Sewing and rayon embroidery threads carry OEKO-TEX® certification, and the factory produces about 35,000 tons of sewing thread and 3,500 tons of embroidery thread a year, so repeat orders come from the same dye lab.
Since 1999, MH has grown into 9 factories across roughly 350,000 m², with 3,000+ employees, 2,000+ partner manufacturers and around 10,000 tailoring materials shipped to 150+ countries under the MH and TWO BIRDS trademarks. It's recognized as a "Top 500 China Service Industry" company and an "AAA Trustworthy Company", which is the depth behind its "Kingdom of Sewing" name. Embroidery factories can also source the floss, Aida cloth and hoops that go into kits from the same supplier.
Garment manufacturers, embroidery workshops, uniform makers and craft-kit brands can browse the thread range, read more about MH, or contact MH for a quote by thread type, count, color and quantity.
Frequently Asked Questions
What is the main difference between sewing and embroidery? Sewing joins pieces of fabric with seams to make a functional product such as a garment, bag or cushion. Embroidery decorates the surface of fabric with stitched designs such as logos and motifs. Sewing uses strong spun thread and seam stitches; embroidery uses smooth, shiny filament thread and decorative stitches like satin and fill, so they differ in both techniques and skill level demands.
Can I use embroidery thread on a sewing machine for seams? It isn't recommended for structural seams. Filament embroidery thread is slick and lighter, so it has less holding power than spun sewing thread of a similar size. Use it only for decorative topstitching that carries no load, and use spun or core-spun sewing thread for seams that have to survive wear and washing.
Is polyester or rayon embroidery thread better? Rayon has a softer hand and the highest luster, so it suits fashion, lace and premium labels. Polyester holds its color better through bleach and industrial laundering, which makes it the safer choice for workwear, uniforms, hotel linens and children's clothing. 120D/2 is the standard size for both in machine embroidery.
What thread sizes are used for sewing and embroidery? Garment sewing commonly uses spun polyester from 20S/2 (heavy denim and bags) to 60S/3 or 80S/2 (fine fabrics), with 40S/2 the general-purpose size. Machine embroidery typically runs on 120D/2 filament thread, with 75D/2 for fine detail and 150D to 300D for bold fills. Hand embroidery uses 6-strand cotton floss such as 32S/2×6.
What fabric is best for hand embroidery and cross-stitch? Aida cloth is the standard for counted cross-stitch because its woven grid shows exactly where each stitch goes and forms designs by counting threads over a grid. Lower counts such as 9CT have larger squares, which suit beginner kits and bold patterns; higher counts such as 14CT-18CT give finer detail.
