This comprehensive guide on how to sew plain seams will walk you through the essential steps and techniques required to achieve impeccable results. Whether you’re a novice seamstress or a seasoned sewing enthusiast, honing your plain seam skills is essential.
From selecting the right seam allowance to pressing the seam for a polished look, each aspect of sewing a plain seam will be demystified, enabling you to embark on a wide range of sewing projects with confidence.
What is a Plain Seams?
A plain seam, also known as a single or regular seam, is the most basic and commonly used seam in sewing. It involves joining two fabric pieces with their right sides together and sewing along the selected seam allowance using a straight stitch.
Typically, a plain seam is sewn with a 5/8-inch (or 1.5 cm) seam allowance, though this measurement can vary depending on the pattern and project requirements.
Once sewn, the seam allowance can be pressed open or to one side, depending on the project’s specifications. Plain seams are suitable for a wide range of fabrics and applications, making them a fundamental technique in sewing.
They are often used for constructing garment pieces, attaching darts, and joining fabric panels. While plain seams are straightforward, achieving clean and even stitches is crucial for a polished final result, and they serve as the foundation for more advanced seam finishing techniques like French seams or flat-felled seams.
How to Sew Plain Seams?
Here are the simple methods for sewing plain seams:
Prepare Your Fabric
Start by placing your fabric pieces with the right sides facing each other. The right side of the fabric is the side with the pattern or the more vibrant color.
Pin and Align Edges
Pin the fabric pieces together along the edge you want to sew. Ensure that the edges are aligned and that any notches or markings on the pattern match up.
Select a Seam Allowance
Determine the appropriate seam allowance for your project. The standard seam allowance is 5/8 inch (1.5 cm), but it can vary depending on your pattern or project instructions.
Sew the Seam
Using a sewing machine, start at the edge of the fabric and sew a straight stitch along the pinned edge, maintaining the chosen seam allowance. Backstitch at the beginning and end to secure the seam.
Trim Excess Threads and Fabric
Trim any excess thread and fabric, especially at the seam ends, to keep the seam neat.
Press the Seam
After sewing, press the seam open with an iron. This flattens the seam and sets the stitches for a crisp and polished appearance.
Finish as Needed
Depending on your project, you may finish the seam allowances with techniques like serging, pinking, or zigzag stitching to prevent fraying. Alternatively, you can leave the seam allowances as is if the fabric doesn’t fray easily.
These seven steps guide you through sewing a basic plain seam, which is the foundation of many sewing projects. Mastering this fundamental skill will enable you to create clean and sturdy seams in various fabrics and garments.

What Are The Types Of Seams?
There are various types of seams in sewing, each designed to serve specific purposes and accommodate different fabrics and project needs. Here are the types of seams:
Plain Seam
The plain seam, also known as a single or regular seam, is the most basic type. It involves joining two fabric pieces with their right sides together and sewing along the selected seam allowance using a straight stitch.
This seam is versatile and suitable for a wide range of fabrics and projects.
French Seam
A French seam is a method used to encase raw fabric edges, providing a clean and polished finish on both the inside and outside of a garment or item. It is often used with delicate or sheer fabrics to prevent fraying and adds an elegant touch to sewing projects.
Flat-Felled Seam
Commonly found in denim jeans and heavy-duty workwear, flat-felled seams are strong and durable. They involve sewing two fabric layers with right sides together, trimming one seam allowance, folding the remaining one over, and topstitching to create a flat, finished look.
Overlock Seam
Overlock or serged seams are commonly used for finishing edges on woven or knit fabrics. An overlocker or serger machine trims the seam allowance while simultaneously encasing it with a neat, overlocking stitch that prevents fraying.
Bound Seam
Bound seams involve enclosing raw edges with bias tape or binding. This type of seam adds strength and durability and is often used in quilting, home decor, and finishing raw edges in various sewing projects.
Lapped Seam
Lapped seams involve overlapping one fabric edge over another and stitching them together. They are commonly seen in traditional shirt plackets, cuffs, and certain tailored garments, providing a clean and finished edge.
Mock-French Seam:
A mock French seam is a simplified version of the French seam. It involves sewing the wrong sides together first, trimming the seam allowance, and then folding the fabric with the right sides together to encase the raw edges within a second seam, creating a cleaner interior finish.
These types of seams offer a range of options for seam finishing, construction, and design in sewing projects, allowing you to choose the most suitable seam type based on your fabric, project requirements, and desired aesthetic.
