how to sew long strips of fabric togetherTo sew long strips of fabric together easily, start by cutting your strips with a 1/2" seam allowance.

Align two strips at a 90-degree angle, right sides together, and draw a diagonal line across the intersection. Sew directly on that line, creating a sturdy diagonal seam that distributes bulk evenly.

Press the seam open and trim excess fabric. Continue piecing strips directionally – even-numbered strips from one end, odd-numbered from the opposite – for sharp corners and straight edges.

Press seams to one side.

With care, you’ll have beautifully pieced strips ready for your next project.

But there are more tips to guarantee accuracy…

Key Takeaways

  • Cutting precise strips is crucial – align that fabric edge like a laser-guided missile for seamless piecing later on.
  • Mastering the diagonal seam technique is a game-changer. It distributes bulk like a load balancer, leaving no bulky seams to hog the spotlight.
  • Directional sewing? Now that’s a sewing superpower! It keeps those strips marching in formation, preventing them from going rogue and ruining your parade.
  • Pressing matters, my friend. It’s like giving your fabric a spa day, smoothing out all the wrinkles and letting those seams shine like they’ve just stepped off the catwalk.

How to Sew Long Strips of Fabric Together?

To sew long strips of fabric together, first trim the ends to make them even and align the edges carefully. Then, sew the strips together using a 1/4 inch seam allowance, sewing in the same direction for accurate piecing.

Preparing Fabric Strips for Sewing

Preparing Fabric Strips for Sewing
To start, you’ll need to cut strips across the width of your fabric, adding an extra 1/2" to the desired border width. Next, align one strip right side up and place another strip wrong side up on top, ensuring they form a 90-degree angle before drawing a diagonal line and sewing along it.

Cutting Fabric Strips

Cut fabric strips across the width, aligning the edge on the horizontal cutting line of your mat’s measurement grid. Leave selvedges for later trimming and add 1/2" to your desired strip width. Follow these steps:

  1. Smooth fabric on mat
  2. Align fabric edge
  3. Use rotary cutter
  4. Maintain strip alignment

Cutting accurate strips is important for successful strip piecing and seam allowance distribution.

Piecing Strips With Diagonal Seam

You’ll precisely align the strips: place one strip right side up, the other wrong side up on top, aligned at 90 degrees. Draw a diagonal line, pin, and sew on it. This:

  1. Distributes seam bulk evenly
  2. Creates less visible diagonal seams
  3. Allows perfect perpendicular seam alignment
  4. Enables sewing methods like rail fence blocks

Mastering diagonal seam techniques elevates your quilting skills, liberating your creativity with precise fabric alignment.

Sewing Methods for Strip Piecing

Sewing Methods for Strip Piecing
You’ll learn how to use directional sewing to maintain straight seams and sharp corners when piecing long fabric strips. Tracking the sewing direction by alternating the starting end for odd and even-numbered rows prevents seam allowance accumulation and misshapen pieces.

Directional Sewing

Employ directional sewing to maintain straight, accurate strip sets. Sew:

  • Even-numbered strips from one end
  • Odd-numbered strips from the opposite end
  • Seam allowances distribute evenly
  • Sharp corners and straight edges result

With this method, seam bulk doesn’t accumulate, preventing bowing. Your quilt strips will lie flat, enabling precise piecing for professional results.

Tracking Sewing Direction

To track your sewing direction:

  1. Use the selvage edge as a reference line.
  2. Stick a pin with its head pointing toward your starting end.
  3. Alternate beginning ends for odd and even rows.

This guarantees consistency, preventing crooked seams and misaligned corners. With each added strip, simply follow the pin’s direction, swapping ends for the next row. Tracking your path maintains row-to-row accuracy for precision piecing.

Accurate Strip Piecing Using Precut Fabric Strips

After cutting your fabric strips, trim the seam allowances and press the strips flat for accurate piecing. When sewing multiple strips together, use the diagonal seam technique to distribute the bulk evenly and create a less noticeable seam.

Trimming and Pressing

Now that you’ve pieced your fabric strips, it’s time to trim and press them. Here are the imperative steps:

  1. Open each sewn strip to check if it’s straight and aligned properly.
  2. Trim any excess fabric, leaving a 1/4" seam allowance for borders or 3/8" for binding.
  3. Carefully trim off the selvedges and any "dog ear" corners.
  4. Press the seam allowances to one side for borders or open for binding.

Piecing Multiple Strips

Piece strips together until desired length is achieved. For borders, cut to correct length after piecing.

  • Use diagonal seam to distribute seam allowance bulk
  • Check strip alignment and fabric type
  • Maintain proper seam allowance and press seams
  • Adjust strip length as needed for accurate piecing

The diagonal seam is less noticeable than a straight seam, ensuring seamless results.

Tips for Cutting Your Own Straight Strips

Tips for Cutting Your Own Straight Strips
Sometimes your fabric strips may be too short for your desired block size, requiring you to extend them. You can extend strips by sewing them together using either a diagonal seam or a binding method.

Extending Fabric Strips

  • Lay one strip right side up horizontally
  • Place the second strip wrong side up vertically, leaving a 1/2" gap
  • Mark a diagonal line from corner to corner
  • Sew on the diagonal line
  • Open to form one long strip, trimming the seam allowance

This diagonal seam method distributes bulk evenly for neater joins. Master this fabric extension technique for perfectly pieced quilts!

Binding Method

To join short strips, here’s an alternative binding method:

  1. Lay one strip right side up, horizontally.
  2. Place the second strip wrong side up, vertically on the first strip’s end, leaving a 1/2" gap.
  3. Fold the second strip over the first, encasing it.
  4. Sew along the fold, joining the strips.
  5. Trim the seam allowance.

This neat binding technique secures seam allowances while extending your strip length.

Frequently Asked Questions (FAQs)

How do I avoid fabric stretching issues?

To avoid fabric stretching, use a walking foot and feed dogs. Go slowly, guiding fabric gently with your hands. For perfect seams, starch and press fabric before sewing. A consistent seam allowance prevents distortion as you sew long strips.

What is the best seam allowance width?

The standard seam allowance width is 1/4 inch (35 mm). This provides ample space for seams to lie flat while preventing excess fabric bulk. For thicker fabrics or projects requiring extra room, consider increasing to 3/8 inch (5 mm) allowance. Consistency is key – stick with one width throughout your project.

How can I ensure perfect mitered corners?

To guarantee perfect mitered corners, mark diagonal seam lines, sew precisely along them, and trim excess fabric. Press seams open and straighten edges for crisp, 90-degree corners. Measure carefully and adjust as needed for an impeccable finish.

Are there techniques for sewing curved strips?

Like a gentle stream curving through a meadow, curved fabric strips open new creative possibilities. With a free-motion quilting foot and practice, you’ll soon be stitching graceful arcs that bring your designs to life.

What thread and needle types work best?

Use a sharp needle and high-quality cotton or polyester thread matched to your fabric weight. Adjust top and bobbin tension so stitches lie flat without puckering. A quality needle and properly tensioned thread guarantee durable, even seams when piecing long strips.


Stitch by careful stitch, you’ll master sewing long strips of fabric together with precision.

Visualize those beautifully pieced strips transforming into stunning quilts or garments – the possibilities are endless.
