6 Essential Stitches Every Sewist Should Know: Stitches for Every Project

Whether you're looking for a sewing machine, or a beginner just getting started, understanding the different types of stitches, their application mode and their purposes can help elevate your sewing game.

Let’s break down the most common machine stitches, when to use them, and why they matter:

1. Straight Stitch (Lockstitch)

Purpose: It's the most common stitch that helps to hold pieces together securely.
Best for:

Joining seams: The primary use for constructing garments, bags, and home decor items.
Topstitching: Creating decorative and functional lines on the outside of your project, adding a professional finish.
Hemming: Creating neat and durable hems on clothing, curtains, and other fabrics.
Basting: Temporarily holding fabric layers together (with a longer stitch length).

Application modes:

- Regular stitching: Use a stitch length of 2.4mm to 3.0mm for general sewing. For thicker fabrics, consider a slightly longer stitch (e.g., 3.0mm).
- Basting and gathering: A longer stitch length of 5.0mm is ideal for these temporary applications, as it's easy to remove.
Pro Tip: Always backstitch at the beginning and end of your seams to secure the stitches and prevent them from unraveling.

2. Zigzag Stitch

Purpose: To prevent fabric edges from fraying, provide stretch for knit fabrics, and add decorative finishes.
Best for:

Stretch fabrics: The inherent give of the zigzag stitch prevents seams from popping when stretched, making it perfect for knits, activewear, and swimwear.
Preventing fraying: Finishing raw edges of woven fabrics where an overlocker (serger) isn't available.
Decorative finishes: Adding unique embellishments, securing appliqués, or creating satin stitches for embroidery.
Reinforcing stress points: Such as securing belt loops or creating sturdy buttonholes (with specific settings).

Application modes:

Regular zigzag: Use a width of 3.0mm to 5.0mm on the edges of fabric to prevent fraying or for joining stretchy fabrics.
Attaching appliqués or securing belt loops: Use a small zigzag width of 2.5mm and a short length of 0.5mm for dense, secure stitching.

3. Overcast Stitch

Purpose: To neaten and secure raw fabric edges, preventing fraying without the need for a overlocker/ serger
Best for:

Neatening seam allowances: Finishing raw edges on wovens to prevent unraveling.
Reducing bulk: Creating flat, less bulky seams, especially useful for garments.

Application modes: Some machines especially those newly bought within the last 10 years, come with a built-in overcast stitch. It sews over the edge of the fabric to prevent fraying and gives your inside seams a professional look.

Pro Tip: Pair your overcast stitch with an overcasting foot (sometimes called an overedge foot) for the best results. This foot has a guide that helps keep your fabric edge aligned and a pin that allows the stitch to form correctly without pulling the fabric.

4. Blind Hem Stitch

Purpose: Invisible hemming that creates small, intermittent stitches that catch only a few threads of the fabric on the right side.

Best for:

Formal wear: Dresses, skirts, and blouses where a discrete hem is desired.
Curtains and drapes: Achieving a clean finish on home decor items.
Dress pants and tailored garments: For a professional and neat appearance.

Application modes: Hem the bottom of your garments so the stitches are barely visible from the outside (they just look like very small dots, and with matching thread color, you can hardly see them). The key is to fold your fabric correctly and adjust your machine settings so the needle just barely catches the main fabric. It requires a bit of testing first and a blind hem foot, but gives a polished finish perfect for professional garments.

5. Buttonhole Stitch

Purpose: Creating neat, reinforced openings for buttons
Best for:

Shirts and blouses: Standard application for closures.
Bags and accessories: Where button closures are used.
Pillows and home decor: Adding functional or decorative buttonholes.

Application modes: Most machines provide automatic or 4-step buttonhole options.

Automatic Buttonholes: For ultimate ease, insert your button into the specialized buttonhole footer. The machine will automatically sew the entire buttonhole in one go, typically using a series of dense zigzag stitches.
4-Step Buttonholes: This method requires you to manually sew each of the four sides of the buttonhole (two parallel lines and two bar tacks) and manually marking the size of the buttonhole required.

6. Decorative Stitches

Purpose: Adding flair and personality
Best for:

Embellishments: Creating borders, edgings, or focal points on garments, quilts, or accessories.
Reinforcing seams: Some decorative stitches can add both strength and visual interest to seams.
Monograms: Personalizing items with initials or names.
Borders and trims: Adding a decorative finish to edges or seams.
Securing appliqués and laces: Beyond just beauty, many decorative stitches can also be used to securely attach appliqués or lace with style.

Application modes: Modern sewing machines come with a vast array of built-in decorative stitches. Experiment with different stitch lengths, widths, and even thread types (like variegated or metallic threads) to achieve various effects.

Final Thoughts: Choose the Right Stitch for the Right Job

Each stitch has a purpose, and knowing which one to use can make your sewing neater, stronger, and more enjoyable. Experiment with your machine’s settings, practice on scrap fabric, and don’t be afraid to try something new!
