Sewing is a timeless craft that has been passed down through generations. Whether you are new to sewing or an experienced seamstress, learning how to sew a flat fell seam is an essential technique to add to your repertoire. A flat fell seam is a sturdy and neat finishing method often used in garment construction, particularly for heavier fabrics such as denim or twill. In this detailed guide, we will take you through the steps of sewing a flat fell seam so that you can achieve professional and polished results in your sewing projects.

Understanding the Flat Fell Seam

The flat fell seam, also known as a flat-felled or felled seam, is a durable and versatile finishing technique commonly used in sewing garments. This type of seam involves two raw edges being folded and encased within itself, creating a flat and neat appearance on both sides of the fabric. The result is a strong and secure seam that can withstand wear and tear, making it ideal for constructing heavy-duty items such as jeans, jackets, and bags.

The beauty of the flat fell seam lies in its versatility. It can be used for joining pieces of fabric together or for finishing raw edges like on the inside of sleeves or pant legs. It provides a clean edge without any visible raw edges, making it perfect for reversible items or garments with visible seams. The finished result also has a professional look that adds an extra level of finesse to your sewing projects.

Materials Needed

Before we dive into the steps of sewing a flat fell seam, it is essential to have all the necessary materials on hand. Here are some items you will need:

1. Fabric – The type of fabric you use for your project will determine how durable your seam will be. For best results, use medium to heavyweight fabrics such as denim, twill, canvas, or wool.

2. Thread – The thread you use should match your fabric to ensure a seamless and unobtrusive seam.

3. Sewing Machine – While it is possible to sew a flat fell seam by hand, using a sewing machine will speed up the process and give you more precise results.

4. Scissors – You will need scissors to cut your fabric and trim excess threads.

5. Ruler or Measuring Tape – A ruler or measuring tape will come in handy when measuring and marking your fabric for sewing.

6. Pins – Pins are essential for holding your fabric pieces together while sewing.

Step by Step Guide to Sewing a Flat Fell Seam

Now that you have all the materials ready, let’s walk through the step-by-step process of sewing a flat fell seam:

Step 1: Prepare Your Fabric

Start by cutting out your fabric pieces according to your pattern, making sure to include seam allowances. Keep in mind that the seam allowance used for a flat fell seam is usually wider than standard seams, so check your pattern instructions for the specific measurement needed. You can also use a ruler or measuring tape to mark the appropriate seam width on your fabric.

Step 2: Place Your Fabric Pieces Right Sides Together

With right sides facing each other, align the edges of your fabric pieces that need to be joined together. Make sure they are perfectly aligned and secure them in place with pins along the seam line.

Step 3: Sew Your First Stitch

Using a straight stitch on your sewing machine, sew along the pinned edge with a seam allowance that matches the width you have marked on your fabric pieces. Be sure to backstitch at both ends of the stitch for added reinforcement.

Step 4: Trim The Seam Allowance

Trim one side of the seam allowance close to the first stitch line, leaving the other side intact with its full width.

Step 5: Press the Seam to One Side

Open the fabric pieces, and with right sides still facing, press the seam towards one side. Use an iron to get a crisp and clean edge. This step is essential in creating a professional-looking flat fell seam.

Step 6: Fold And Press The Remaining Seam Allowance

Take the remaining untrimmed side of your seam allowance and fold it over so that it fully encases your first stitch line. Use your iron to press this seam down firmly, making sure that both raw edges are aligned.

Step 7: Sew The Final Stitch

Using a straight stitch, sew along the folded edge to create a second line of stitching. This stitch should be slightly wider than your first stitch, as it will enclose the raw edges inside the seam. Backstitch at both ends for added strength.

Congratulations – you have now successfully sewn a flat fell seam!

Understanding the Flat Fell Seam Technique

The flat fell seam is a sewing technique that creates a strong, secure finish for seams on garments or other fabric projects. This technique is commonly used in denim or heavy weight fabrics, but can also be used in lighter weight materials. The result is a smooth and professional looking seam with hidden raw edges on the inside of the garment.

Gathering Supplies and Preparing Your Workspace

Before attempting to sew a flat fell seam, it’s important to make sure you have all the necessary supplies and a clean workspace. You will need:

– A sewing machine
– A sharp pair of fabric scissors
– Pins or clips
– Sewing thread that matches your fabric
– Fabric pieces to be sewn together

Make sure your sewing machine is in good working condition and has a fresh needle appropriate for the type of fabric you will be using. It’s also important to clean and clear your workspace so you have enough room to spread out your fabric.

Preparing Your Fabric

To achieve a perfect flat fell seam, it’s important to prepare your fabric correctly. Start by prewashing your fabric to prevent any shrinkage after sewing. Once washed, iron out any wrinkles and lay out your fabric pieces with the right sides facing each other.

Then, using your pins or clips, secure the edges of your fabric pieces together where you will be sewing the flat fell seam. This will help keep the edges aligned and prevent shifting while sewing.

How To Sew A Flat Fell Seam Step by Step

Step 1: Begin by sewing a regular straight stitch about ⅜ inch from the raw edge of both pieces of fabric that you are joining together. Use a stitch length between 2-3 for best results.

Step 2: Once both pieces are sewn together, press open the seam allowance. This will ensure that the seam will lay flat and straight when completed.

Step 3: Trim one side of the seam allowance to about ⅛ inch, leaving the other side at its original width.

Step 4: Fold the wider seam allowance over the narrow one, enclosing it inside. Press this fold in place, making sure the raw edge of the narrower seam allowance is fully covered.

Step 5: On your sewing machine, topstitch along the folded edge, securing both seam allowances together. Use a stitch length between 3-4 for a clean and secure finish.

That’s it! You have successfully completed a flat fell seam.

Tips for Perfecting Your Flat Fell Seam

To achieve a flawless flat fell seam, here are some additional tips to keep in mind:

– It’s important to take your time with each step and make sure your fabric is aligned and pressed properly.
– Be sure to backstitch at the beginning and end of your stitches for added strength.
– Use a denim needle when sewing heavy weight fabrics to prevent any breakage or skipped stitches.
– Practice on scrap fabric first before attempting a flat fell seam on your final project.
– Adjust your stitch length if needed depending on the weight of your fabric. A shorter stitch length may be necessary for thicker fabrics.
– If you do not have a sewing machine, you can still achieve a flat fell seam by hand stitching using backstitch or slip stitch techniques.

When To Use A Flat Fell Seam

The flat fell seam is not only aesthetically pleasing but also adds durability and strength to any garment or fabric project. It’s commonly used in constructing denim jeans, jackets, bags, and other heavy weight items that require extra reinforcement. However, it can also be used in lighter weight fabrics when you want a clean finish with no raw edges exposed.

Congratulations, you have now mastered the art of sewing a flat fell seam. With practice and patience, this technique will become second nature to you and add a professional touch to all your sewing projects. Remember to gather all necessary supplies, prepare your fabric correctly, and take your time with each step for best results. Happy sewing!
