How To Make Bias Strips

How to Make Bias Strips: A complete walkthrough for Sewing Enthusiasts

Creating bias strips might seem like a small detail in the world of sewing, but mastering this technique unlocks a whole new level of creativity and precision. Bias strips, cut at a 45-degree angle to the fabric's grain, offer unparalleled drapability and flexibility, making them perfect for binding, facings, and creating beautiful curved seams. This thorough look will take you through every step, from selecting the right fabric to finishing your perfectly pressed bias strips, ensuring you're equipped to tackle any project with confidence. This guide covers everything from basic techniques to advanced tips for working with different fabric types and achieving professional results.

Understanding Bias and its Advantages

Before diving into the process, let's understand what makes bias strips so special. A fabric's grain refers to the direction of the warp (lengthwise) and weft (crosswise) threads. Cutting on the bias, at a 45-degree angle to these threads, allows the fabric to stretch and curve more readily than when cut straight of grain.

• Binding edges: Creating a clean, professional finish on seams and edges, especially on curved pieces.
• Facing garments: Providing a neat and secure finish on garment openings.
• Creating bias tape: A versatile trim used for various decorative and functional purposes.
• Appliqué: Adding beautifully flowing and curved shapes to your projects.
• Adding ruffles and flounces: Achieving a soft, elegant drape.

Choosing Your Fabric and Tools

The success of your bias strips hinges on selecting the right fabric and using the appropriate tools. Let's explore these crucial aspects:

Fabric Selection:

The type of fabric you choose will significantly influence the final look and feel of your bias strips. Consider:

• Fabric weight: Lighter fabrics are easier to work with and create softer bias strips, ideal for delicate projects. Heavier fabrics, like denim or canvas, will result in sturdier strips but require more precision when cutting and pressing.
• Fabric type: Woven fabrics generally work best for bias strips, although some knit fabrics can also be used. Avoid fabrics that are overly stretchy or prone to fraying excessively.
• Pre-washing: Always pre-wash your fabric to prevent shrinkage after your bias strips have been sewn into your project.

Essential Tools:

• Rotary cutter: A rotary cutter provides precise and efficient cutting, especially useful for creating long, continuous bias strips.
• Self-healing cutting mat: Protects your work surface and ensures clean cuts.
• Ruler: A clear ruler, ideally with markings for 45-degree angles, is essential for accurate cutting.
• Iron and ironing board: Pressing is critical for creating neat and professional-looking bias strips. Use a steam iron for best results.
• Pins: Essential for holding the fabric together while cutting and sewing.
• Scissors: For trimming and snipping.
• Seam ripper: For correcting mistakes.

Cutting Bias Strips: Different Techniques

There are two primary methods for cutting bias strips:

Method 1: Cutting Individual Strips

This method is suitable for smaller projects or when you need a specific number of bias strips.

1. Fold the fabric: Fold your fabric in half, aligning the selvages (the finished edges of the fabric). You'll be cutting along the diagonal line formed by the fold.
2. Mark the 45-degree angle: Use your ruler to mark a 45-degree angle along the folded edge. Most rulers have markings to assist with this.
3. Cut the strips: Use your rotary cutter to cut along the 45-degree line, creating strips of your desired width (typically 1.5" to 2" wide for binding). Continue cutting parallel strips until you have the required quantity. Remember to maintain consistency in your cutting angle for uniform strips.

Method 2: Cutting Continuous Bias Strips

This method is more efficient for larger projects requiring extensive amounts of bias strips.

1. Determine the length: Cut a square or rectangle from your fabric. The size depends on how much bias you need. A larger piece yields more bias strips.
2. Cut a bias strip from one corner: Cut a bias strip of the desired width starting from one corner.
3. Rotate the fabric: After cutting one strip, rotate the fabric 90 degrees. You can now cut another strip parallel to the first one, extending the continuous bias strip.
4. Repeat: Continue rotating the fabric and cutting bias strips, creating a continuous length of bias.

Pressing and Finishing Bias Strips

Once you've cut your bias strips, pressing is crucial for creating a professional finish. Proper pressing ensures your bias strips lie flat and prevents distortion during sewing.

1. Press the strips: Use your iron to press each bias strip flat. This helps to set the bias and removes any wrinkles or creases.
2. Prepare for binding (optional): If you're using the strips for binding, you can press them in half lengthwise, creating a crisp crease. This makes them easier to sew and gives a neater finished look. You can then press the edges of this folded strip inwards to create a double folded edge for clean binding.
3. Stitch in the ditch (optional): For added durability, especially with heavier fabrics, you might consider stitching in the ditch – this technique involves stitching along the seam line created by the double folded bias binding.

Advanced Techniques and Tips

• Using a bias tape maker: A bias tape maker is a tool designed to quickly and efficiently create bias tape. These tools come in various sizes.
• Working with different fabrics: Delicate fabrics like silk might require careful handling during cutting and pressing. Use a low-heat setting on your iron. Heavier fabrics may need a more firm press.
• Preventing fraying: For fabrics that fray easily, finish the edges of your bias strips with a zigzag stitch or pinking shears to prevent unraveling.
• Joining bias strips: If you run out of bias strip, you can smoothly join them by overlapping the ends at a 45-degree angle. Press the seam flat, ensuring a smooth transition.

Frequently Asked Questions (FAQ)

Q: What is the best width for bias strips?

A: The optimal width depends on your project. Think about it: for binding, 1. And 5" to 2" is common. For other applications, adjust the width accordingly.

Q: Can I use a regular sewing machine to sew bias strips?

A: Yes, a standard sewing machine is perfectly suitable for sewing bias strips.

Q: How do I prevent stretching while sewing bias strips?

A: Use a gentle touch and carefully stretch the fabric slightly to prevent puckering while sewing. Ensure even tension on your sewing machine.

Q: Can I use knit fabrics for bias strips?

A: While less common, some stable knit fabrics can work. On the flip side, their stretchiness may affect the final result. Consider a knit fabric with minimal stretch.

Q: Why is pressing so important?

A: Pressing ensures the bias strips are flat and prevents distortion, leading to a professional and neat finish.

Conclusion

Creating bias strips is a fundamental skill for any serious sewist. Don't hesitate to experiment with different fabrics and techniques to discover what works best for you and your unique style. The more you work with bias strips, the more confident and proficient you'll become in creating stunning, professional-quality results. Remember, practice makes perfect. By mastering these techniques, you tap into a world of possibilities for enhancing your projects with beautifully draped and flowing details.
