This comprehensive guide will walk you through the essential steps and provide valuable tips to confidently sew spandex and create beautiful, durable garments.
## Understanding Spandex Fabric
Before diving into the sewing process, it’s crucial to understand the properties of spandex fabric. Spandex is typically blended with other fibers like nylon, polyester, or cotton to enhance its performance and aesthetics. The percentage of spandex in the blend determines the fabric’s stretch and recovery. Higher spandex content generally means greater elasticity.
**Types of Spandex Fabric:**
* **Nylon Spandex:** This blend is known for its durability, moisture-wicking properties, and smooth texture. It’s commonly used in swimwear, activewear, and lingerie.
* **Polyester Spandex:** Polyester spandex is more resistant to fading and stretching out compared to nylon spandex. It’s a good choice for garments that require frequent washing and wear.
* **Cotton Spandex:** Cotton spandex offers the comfort and breathability of cotton with the added stretch of spandex. It’s suitable for everyday clothing, such as t-shirts, leggings, and dresses.
* **Swimsuit Spandex:** Specifically designed for swimwear, this type of spandex is chlorine-resistant and offers excellent shape retention.
* **Power Mesh:** A lightweight, sheer fabric with high spandex content, often used for lining, shapewear, and creating supportive panels in garments.
**Key Characteristics of Spandex:**
* **Stretch and Recovery:** Spandex can stretch significantly without losing its original shape.
* **Shape Retention:** It returns to its original form after being stretched.
* **Drape:** Spandex fabrics often have a fluid and flattering drape.
* **Breathability:** Depending on the blend, spandex fabrics can offer varying degrees of breathability.
* **Durability:** Spandex is generally durable, but it can be susceptible to damage from heat and chlorine.
## Essential Tools and Supplies
Having the right tools and supplies is essential for successful spandex sewing. Here’s a list of what you’ll need:
* **Sewing Machine:** A sewing machine with adjustable stitch length and width is necessary. A serger is highly recommended for finishing seams and creating a professional look, but it’s not essential.
* **Ballpoint or Stretch Needle:** These needles have a rounded tip that prevents them from snagging or damaging the spandex fibers. Choose the appropriate size based on the fabric weight.
* **Polyester Thread:** Polyester thread has some give and is less likely to break than cotton thread when the fabric stretches. Use a high-quality thread for best results.
* **Walking Foot or Roller Foot:** A walking foot helps feed the fabric evenly through the machine, preventing stretching and distortion. A roller foot can also be helpful.
* **Clear Elastic:** Clear elastic is perfect for stabilizing seams and preventing them from stretching out, especially in areas like necklines, armholes, and waistbands.
* **Pins or Clips:** Use fine pins or fabric clips to hold the fabric pieces together. Avoid using pins that are too thick, as they can leave holes in the fabric.
* **Rotary Cutter and Mat:** A rotary cutter and mat provide a precise and efficient way to cut spandex fabric.
* **Ruler or Measuring Tape:** Accurate measurements are crucial for creating well-fitting garments.
* **Seam Ripper:** A seam ripper is essential for correcting any mistakes.
* **Iron and Ironing Board:** Use a low-heat setting to iron spandex fabric. Avoid over-ironing, as it can damage the fibers.
* **Pattern:** Choose a pattern specifically designed for stretch fabrics. Ensure the pattern includes seam allowances suitable for spandex.
* **Scissors:** Sharp fabric scissors are necessary for trimming seams and other tasks.
* **Cutting Table:** A large, flat surface is essential for cutting out fabric accurately.
## Preparing Spandex Fabric
Proper preparation is key to achieving successful sewing results with spandex.
1. **Pre-Wash:** Wash the spandex fabric according to the manufacturer’s instructions to pre-shrink it and remove any finishes. This will prevent the garment from shrinking or changing shape after it’s sewn.
2. **Dry Carefully:** Dry the fabric on a low heat setting or hang it to dry. Avoid over-drying, as it can damage the fibers.
3. **Iron on Low Heat:** Use a low-heat setting to iron the fabric. Avoid over-ironing, as it can damage the fibers. Test a small area first to ensure the iron doesn’t melt or scorch the fabric.
4. **Lay Out the Pattern:** Place the pattern pieces on the fabric according to the pattern instructions. Pay attention to the grainline, which indicates the direction of the fabric’s stretch.
5. **Pin or Clip Securely:** Use fine pins or fabric clips to secure the pattern pieces to the fabric. Make sure the fabric is lying flat and smooth.
6. **Cut Accurately:** Use a rotary cutter and mat or sharp fabric scissors to cut out the fabric pieces. Cut along the pattern lines carefully to ensure accurate sizing.
## Sewing Techniques for Spandex
Sewing spandex requires specific techniques to prevent stretching, puckering, and skipped stitches.
1. **Choose the Right Needle:** Use a ballpoint or stretch needle specifically designed for stretch fabrics. These needles have a rounded tip that prevents them from snagging or damaging the spandex fibers. A size 75/11 or 80/12 is generally suitable for most spandex fabrics. Change your needle regularly to avoid skipped stitches and fabric damage.
2. **Use the Correct Thread:** Polyester thread is the best choice for sewing spandex. It has some give and is less likely to break than cotton thread when the fabric stretches. Use a high-quality thread for best results and to prevent seam failure.
3. **Adjust Stitch Length and Width:** A shorter stitch length is generally recommended for spandex. A stitch length of 2.0 to 2.5 mm is a good starting point. A slightly wider stitch width can also help prevent puckering. Experiment with different stitch lengths and widths on a scrap of fabric to find the optimal settings for your machine and fabric.
4. **Reduce Presser Foot Pressure:** Reducing the presser foot pressure can help prevent the fabric from stretching as it’s being sewn. If your machine has adjustable presser foot pressure, reduce it slightly. You can also try using a Teflon foot, which glides more easily over the fabric.
5. **Use a Walking Foot or Roller Foot:** A walking foot helps feed the fabric evenly through the machine, preventing stretching and distortion. It has feed dogs on both the top and bottom, which grip the fabric and move it along together. A roller foot can also be helpful, as it rolls over the fabric instead of dragging it.
6. **Stretch the Fabric Slightly:** As you sew, gently stretch the fabric slightly in front of and behind the needle. This will help prevent puckering and ensure that the seams have enough give. Be careful not to over-stretch the fabric, as this can distort the shape of the garment.
7. **Sew Slowly and Steadily:** Sewing slowly and steadily will give you more control over the fabric and prevent skipped stitches. Avoid pulling or pushing the fabric through the machine, as this can cause stretching and distortion.
8. **Use a Serger for Seam Finishing:** A serger is ideal for finishing seams on spandex fabrics. It trims the fabric, sews the seam, and overlocks the edges in one step, creating a clean and durable finish. If you don’t have a serger, you can use a zigzag stitch or a serger stitch on your sewing machine to finish the seams.
9. **Stabilize Seams with Clear Elastic:** Clear elastic is a great way to stabilize seams and prevent them from stretching out, especially in areas like necklines, armholes, and waistbands. Simply stitch the clear elastic along the seamline as you sew. Use a zigzag stitch to allow the elastic to stretch with the fabric.
10. **Backstitch or Secure Seams:** Always backstitch at the beginning and end of each seam to secure the stitches. You can also use a knotting tool or hand-tie the threads to prevent the seams from unraveling.
11. **Press Seams Carefully:** Use a low-heat setting to press the seams. Avoid over-ironing, as it can damage the fibers. Use a pressing cloth to protect the fabric from direct heat. Press the seams open or to one side, depending on the pattern instructions.
## Tips and Tricks for Sewing Spandex
Here are some additional tips and tricks to help you master sewing spandex:
* **Practice on Scrap Fabric:** Before sewing your actual garment, practice on a scrap of the same fabric to get a feel for how it behaves and to adjust your machine settings accordingly.
* **Use a Sharp Cutting Tool:** A sharp rotary cutter and mat or fabric scissors are essential for cutting spandex fabric accurately. Dull cutting tools can snag or tear the fabric.
* **Cut Fabric in a Single Layer:** Cutting fabric in a single layer will help prevent it from shifting and distorting. If you need to cut multiple layers, use pattern weights to hold the fabric in place.
* **Use a Lightweight Fusible Interfacing:** If you need to add structure to certain areas of your garment, such as collars or cuffs, use a lightweight fusible interfacing specifically designed for stretch fabrics. This will provide support without adding bulk or stiffness.
* **Consider Lining Your Garment:** Lining your garment can add comfort, support, and opacity. Choose a lightweight, breathable lining fabric that has similar stretch properties to the spandex.
* **Use Pattern Weights:** Pattern weights are helpful for holding the pattern pieces in place while you cut the fabric. They are less likely to distort the fabric than pins.
* **Baste Seams Before Sewing:** Basting seams before sewing can help ensure that the fabric layers are aligned correctly and prevent shifting during the sewing process.
* **Use a Seam Guide:** A seam guide can help you sew straight and consistent seams. You can purchase a seam guide or create your own using masking tape.
* **Don’t Over-Stretch the Fabric:** Be careful not to over-stretch the fabric while you’re sewing. This can distort the shape of the garment and create uneven seams.
* **Take Your Time:** Sewing spandex requires patience and attention to detail. Take your time and focus on each step of the process.
* **Use a Stretch Hem:** When hemming spandex garments, use a stretch hem stitch on your sewing machine or a coverstitch machine to create a flexible and durable hem.
