The Complete Guide to Sewing Machine Stitches: Everything You Need to Know

Master 19 Essential Stitches, Troubleshoot Problems, and Choose the Right Settings for Every Fabric

Modern sewing machines offer incredible versatility with dozens of stitch options. While this variety opens creative possibilities, it can feel overwhelming when you’re starting out. This comprehensive guide will help you understand which stitches to use, when to use them, and how to troubleshoot common problems.

Understanding Your Sewing Machine’s Stitch Options

Why Do Sewing Machines Have Different Stitches?

Sewing machines offer multiple stitches because different projects require different solutions. A straight stitch works perfectly for basic seams, but it would snap when used on stretchy fabrics like jersey knits. Decorative stitches add personality to projects, while utility stitches solve specific construction challenges.

Think of stitches as tools in a toolbox. Just as you wouldn’t use a hammer for every job, you shouldn’t rely on just one stitch type for all your sewing needs.

What Does “12 Stitch Sewing Machine” Mean?

When manufacturers advertise a “12 stitch sewing machine,” they’re telling you how many built-in stitch patterns the machine offers. Entry-level machines typically include 10-25 stitches, covering essential needs. Higher-end models may feature 50-400+ stitches, including decorative patterns and specialty functions.

Here’s what you actually need:

• Beginners: 10-20 stitches are plenty
• Intermediate sewers: 25-50 stitches provide good variety
• Advanced users: 50+ stitches for specialized projects

Essential Sewing Machine Stitches

The Straight Stitch: Your Workhorse

The straight stitch is the most basic and frequently used stitch on any sewing machine. This fundamental stitch creates a line of even stitches in a straight pattern, making it perfect for most construction tasks.

Best uses for straight stitch:

• Constructing seams in garments
• Hemming lightweight to medium fabrics
• Topstitching and decorative lines
• Basting (temporary stitching)
• Quilting straight lines

Stitch length recommendations:

• Lightweight fabrics: 1.5-2.5mm (silk, chiffon, voile)
• Medium-weight fabrics: 2.5-3mm (cotton, linen, wool)
• Heavy fabrics: 3-4mm (denim, canvas, upholstery)
• Basting: 4-5mm for easy removal

The Zigzag Stitch: Versatile and Essential

The zigzag stitch moves the needle from side to side while moving forward, creating a pattern that looks like the letter “Z” repeated. This stitch offers built-in stretch, making it invaluable for modern sewing.

What do you use a zigzag stitch for?

• Finishing raw edges to prevent fraying
• Sewing stretch and knit fabrics
• Creating buttonholes
• Attaching elastic
• Appliqué work
• Mending tears and holes

Zigzag vs. straight stitch differences:

• Flexibility: Zigzag stitches stretch with fabric; straight stitches don’t
• Edge finishing: Zigzag encases raw edges; straight stitches can’t
• Fabric compatibility: Zigzag works on all fabric types; straight stitch may break on stretchy materials
• Decorative potential: Zigzag can be decorative; straight stitch is purely functional

Zigzag stitch settings:

• Narrow zigzag (1-2mm width): Stretch seams, delicate edge finishing
• Medium zigzag (3-4mm width): Standard edge finishing, buttonholes
• Wide zigzag (5-6mm width): Heavy fabric edges, decorative effects

Triple Straight Stitch: Extra Strength

The triple straight stitch (also called triple stretch stitch) sews forward two stitches, back one stitch, creating an incredibly strong seam. Each stitch is reinforced three times, making it perfect for high-stress areas.

What is a triple straight stitch used for?

• Reinforcing seams in activewear and sportswear
• Sewing stretch fabrics without a serger
• Strengthening areas like crotch seams and armholes
• Creating durable topstitching on jeans and heavy fabrics
• Professional-looking flat-fell seams

Utility Stitches for Specific Tasks

Overcast and Overcasting Stitches

What stitch to use for raw edges?

Overcast stitches prevent fabric from fraying by wrapping thread around the raw edge. These stitches mimic the function of a serger on a regular sewing machine.

What stitches can an overlocker do? While traditional overlockers (sergers) create 3-thread, 4-thread, and 5-thread stitches, modern sewing machines offer overcast alternatives:

• Mock overlock stitch
• Overcast stitch
• Blanket stitch for edges

Blind Hem Stitch: Nearly Invisible Hems

The blind hem stitch creates professional-looking hems with minimal visible stitching on the right side of the fabric. This stitch catches just a few threads of the main fabric while securing the hem fold.

Which sewing machine stitches for hemming?

• Blind hem stitch: Best for invisible hems on pants, skirts, curtains
• Straight stitch: Simple hems on casual garments
• Twin needle hem: Professional stretch hem on knits
• Rolled hem: Delicate fabrics using special presser foot

What machine stitch is best for hemming? For most projects, the blind hem stitch provides the most professional results. However, the best choice depends on your fabric and desired appearance.

Buttonhole Stitches

Modern machines offer automatic or manual buttonhole functions. The machine creates dense zigzag stitches that form the buttonhole’s sides and bar tacks at each end.

Types of buttonholes:

• Standard buttonhole: Most common, works for most buttons
• Keyhole buttonhole: For thick shank buttons on coats
• Stretch buttonhole: For knit fabrics
• Bound buttonhole: Hand-finished technique for formal wear

Stretch and Specialty Stitches

Working with Stretch Fabrics

What stitch to use for stretchy fabric?

Regular straight stitches will break when stretch fabrics are pulled. Instead, use these stretch-friendly options:

• Narrow zigzag (1-2mm width): Mimics serger stitches
• Lightning stitch: Built-in stretch stitch on many machines
• Triple zigzag: Extra stretch and durability
• Stretch overlock: Combines seaming and edge finishing

Understanding Specialty Stitches

What is fagoting in sewing? Fagoting is a decorative stitch that joins two pieces of fabric with an open, lacy effect between them. The fabrics are placed slightly apart, and the fagoting stitch creates decorative threads bridging the gap. This technique is often used in heirloom sewing and vintage-style projects.

Machine Settings and Setup

How Do I Know What Settings to Use?

Choosing the right settings depends on several factors:

Fabric weight and type:

• Delicate fabrics: Shorter stitch length, lower tension
• Heavy fabrics: Longer stitch length, potentially higher tension
• Stretch fabrics: Zigzag or stretch stitches, balanced tension

Thread and needle compatibility: The relationship between these three elements affects stitch quality significantly.

What is the difference between sewing needle 90/14 and 80/12? The numbers refer to needle size – 80/12 is smaller than 90/14. The first number is European sizing, the second is American. Use 80/12 for medium-weight cotton fabrics and 90/14 for slightly heavier materials like denim or multiple layers.

For comprehensive needle selection guidance, Schmetz, the world’s leading needle manufacturer, provides detailed compatibility charts and technical specifications that help ensure optimal stitch quality across all fabric types.

How to Set Up Your Machine for Different Stitches

How do you set the sewing machine to produce different stitches?

For mechanical machines:

1. Turn the stitch selection dial to your desired pattern
2. Adjust stitch length using the length dial
3. Set stitch width for zigzag patterns
4. Choose appropriate presser foot

For computerized machines:

1. Use the display panel to select stitch type
2. Adjust settings using + and – buttons
3. Machine may automatically set optimal length/width
4. Install recommended presser foot

Tension Settings for Different Fabrics

What tension should I use for heavy fabric?

Heavy fabrics often require slightly loosened tension to accommodate their thickness. Start with your machine’s default setting (usually 4), then adjust:

• Heavy fabrics: Try tension 3-3.5
• Multiple layers: May need tension 2.5-3
• Thick threads: Often require lower tension
• Lightweight fabrics: May need tension 4.5-5

Signs of incorrect tension:

• Too tight: Fabric puckers, bobbin thread shows on top
• Too loose: Loops appear on top, messy stitches
• Unbalanced: One thread pulls the other through to wrong side

Singer’s technical experts emphasize that proper thread tension creates balanced stitches where both threads meet in the middle of the fabric layers, with neither thread visible on the wrong side of the project.

Troubleshooting Common Stitch Problems

When Stitches Go Wrong

Before adjusting tension or settings, check these common culprits:

1. Threading Issues (Most Common Cause)

• Rethread the entire machine with presser foot UP
• Check that thread flows freely from spool
• Ensure thread passes through all guides
• Verify bobbin is inserted correctly

2. Needle Problems

• Change to a fresh needle (every 8-10 hours of sewing)
• Check needle size matches fabric weight
• Ensure needle is fully inserted and tightened
• Use correct needle type (ballpoint for knits, sharp for wovens)

3. Machine Maintenance

• Clean lint from bobbin area after every few projects
• Oil machine according to manual instructions
• Check for bent or damaged parts

Advanced Stitch Techniques

How to double overlock stitch? A double overlock combines two rows of overlock stitching for extra security on very stretchy or loose-weave fabrics. This is typically done on sergers, but some high-end sewing machines offer similar functions.

What is the longest stitch on a sewing machine? Most machines offer stitch lengths up to 6mm, with some extending to 7mm. Long stitches are used for:

• Basting (temporary stitching)
• Gathering fabric
• Decorative topstitching
• Quilting large areas quickly

How to do a 3/4 stitch? This term typically refers to cross-stitch embroidery rather than machine stitching. However, some computerized machines offer partial decorative stitches that can create similar effects.

Industrial vs. Home Machine Stitches

Do Industrial Sewing Machines Only Do Straight Stitch?

Not all industrial machines are limited to straight stitches, but many are specialized for specific functions:

• Single-needle machines: Usually straight stitch only, built for speed and durability
• Overlock/serger machines: Create multiple thread overlock stitches
• Zigzag industrials: Heavy-duty zigzag for thick materials
• Specialty machines: Buttonhole, blind hem, or decorative stitch specialists

Industrial machines excel at doing one thing exceptionally well, rather than offering versatility like home machines.
