Creating a Professional-Looking Finish with French Seams

When it comes to sewing, achieving a professional-looking seam is essential. One technique that can help you achieve this is the French Seam. French Seams are often used in clothing and other fabric-based projects where the seam will be visible and a neat finish is desired. In this blog post, we’ll explore what French Seams are, what they’re used for, and how to make them.

What is a French Seam?

A French Seam is a type of seam that encloses the raw edges of the fabric within the seam itself, creating a clean and professional finish. This technique is often used on lightweight or sheer fabrics, as well as on fabrics that fray easily. French Seams are commonly used in clothing, such as blouses, dresses, and skirts, as well as in home decor projects like curtains and pillowcases.

Benefits of French Seams

The main benefit of using French Seams is the neat and professional appearance they create. This technique is perfect for creating seams that will be visible on the finished project, as well as for creating seams that need to be strong and durable. French Seams are also great for fabrics that are prone to fraying, as they enclose the raw edges within the seam, preventing fraying.

How to Make a French Seam

Here are the steps to create a French Seam:

Step 1: Check you pattern to see what the sewing allowances are.  We have 5/8″ seam allowance for our pattern, then we double it and so we’ll allow and adjust to 1″ for the total seam allowance throughout the pattern.  1/2″ for this first step.

Unlike a plain seam, we will place the fabric with the wrong sides of the fabric facing each other, stitch a seam along the edge of the fabric, using a 1/2 inch seam allowance.

Step 2: Trim the seam allowance to 1/8 inch.

Step 3: Press the seam to one side, and then turn the fabric so that the right sides are facing each other.

Step 4: Wrong sides toward the inside, fold the fabric along the seam line, so that the seam you just sewed is in the center of the fold. Pin the fabric in place.

Step 5: Stitch a second seam along the fold, using a 3/8 inch seam allowance, enclosing the raw edges within the seam. Check to make sure you have seamed enough seam allowance, so that you can not see the frayed edges, then continue.

Step 6: Press the seam to one side, and your French Seam is complete!

French Seams are a useful and versatile technique that can be used to create a professional-looking finish on a variety of fabric-based projects. By following the steps above, you can easily create French Seams in your sewing projects. Experiment with different fabrics and projects to see how this technique can elevate your sewing skills to the next level.

HI. I'M MARGIE I love creating and creations of all kinds! I love Jesus, I love my family and I love to teach! That's what makes life exciting for me and that is why I have so much to share with you. I am founder and owner of SewingPatternSecrets LLC, based in Boston, MA. I am a writer and an avid sewist with a background in fine art and design from New England School of Art and Design, Boston. Sewing Patterns Secrets was conceived with my husband (my #1 supporter), inspired partly from my grandmother, but largely inspired by my mother, who passed in 2017. She supported many decades of my artistry, including, but not limited to, sewing. Whilst my mother was indeed, an important benefactor, my husband has unfailingly supported all of my endeavours and is the Director of Sales. As the Product and Project Director, I conceptualized, developed, produced, tested, and edited all of the 125+ curated sewing patterns, instructions and ebooks, using my decades of experience. I managed a team of fashion designers to help me with the 3D software and production. I and three other master seamstresses, vector artists, graphic designers, and one amazing fashion illustrator. Production took two solid years of detail and hard work and another six months of sales funnel creation. I give thanks to: Fer, Rima, Oksana, Debbie, Kathreen, Suanne, Elizabeth, Jacki, Bronwen, Kimberly, and the many others who contributed. As such, I am gifted with the ability to share with you my expertise and everything that I have learned along the way, as relates not only sewing, but to project and product creation and all areas of design: web, graphic, fashion, pattern and product creation. This would include 10s of software, marketing and SEO tools, affiliate marketing and so much more. All you have to do is ask! In addition to writing all of the ebooks for Sewing Pattern Secrets, I am also the main writer of this blog, but looking for other (Human) sewing bloggers who would like to partner with us. We welcome guest bloggers, vloggers, influencers and also an invitation to blog for you as well. We always want your advice and we also want to hear from you regarding ideas and improvements to our blog, product, or advertising. PLEASE COMMENT. Please do write me at Blessings, Margie "Make it your goal to live a quiet life, minding your own business and working with your hands, just as we instructed you." 1 Thessalonians 4:11 (coming soon)
