Sewing swimwear requires the right needle to handle stretchy, delicate fabrics without causing damage. But what needle should you use for swimwear?
A ballpoint or stretch needle1 is the best choice for swimwear because it glides between fabric fibers instead of piercing them, preventing snags and skipped stitches.
Using the right needle ensures smooth stitching and durable seams. Let’s explore the different types and how to choose the best one for your swimwear project.
Why are ballpoint and stretch needles ideal for swimwear?
Ballpoint and stretch needles are specifically designed for knit and stretch fabrics like those used in swimwear.
Ballpoint needles have a rounded tip that slides between fabric fibers, preventing snags and holes. Stretch needles are similar but have a special eye and scarf to prevent skipped stitches on highly elastic fabrics.
Both types work well with nylon, spandex, and other swimwear materials. They create flexible seams that stretch with the fabric, ensuring comfort and durability.
Ballpoint vs. Stretch Needles: What’s the Difference?
Although they seem similar, ballpoint and stretch needles have different uses:
- Ballpoint Needles: Ideal for general knits and less stretchy fabrics. The rounded tip prevents fabric damage and skipped stitches.
- Stretch Needles: Designed for highly elastic fabrics like spandex. They have a deeper scarf to prevent skipped stitches and ensure smooth, even stitching.
For swimwear, stretch needles are generally the better choice, especially for fabrics with high elasticity. However, ballpoint needles work well for less stretchy components like lining.
What size needle is best for swimwear fabrics?
Needle size matters because swimwear fabrics are lightweight and stretchy, requiring a delicate touch.
The best needle size for swimwear is 75/11 or 90/142. A 75/11 needle is perfect for lightweight fabrics, while a 90/14 needle is better for thicker or layered swimwear materials.
Choosing the right size prevents skipped stitches, fabric pulls, and uneven seams, ensuring a smooth sewing experience.
How to Choose the Right Needle Size
Consider the fabric weight and stretch when selecting a needle size:
- 75/11: Best for lightweight, thin swimwear fabrics like nylon or single-layer spandex.
- 90/14: Suitable for thicker swimwear materials or when sewing through elastic and multiple layers.
If you’re unsure, start with a 75/11 needle and test on a fabric scrap. If the stitches are uneven or skipped, switch to a 90/14 needle for better stability.
Can you use a universal needle for swimwear?
While a universal needle is versatile, it’s not ideal for swimwear because it lacks the rounded tip needed for stretchy fabrics.
A universal needle has a slightly rounded tip but can still cause skipped stitches and snags on elastic materials.
Using a ballpoint or stretch needle1 is a safer choice, ensuring smooth stitching and preventing fabric damage.
Why Avoid Universal Needles for Swimwear
Universal needles are designed for general-purpose sewing and don’t have the flexibility required for swimwear fabrics. Here’s why:
- Skipped Stitches: Universal needles can’t adapt to the stretchiness of swimwear fabrics, causing uneven stitches.
- Fabric Damage: The sharper tip can pierce through elastic fibers, causing snags and holes.
- Poor Seam Strength: Without the flexibility of a stretch needle, seams may break when the fabric stretches.
While convenient, universal needles compromise the durability and appearance of swimwear. Investing in stretch or ballpoint needles guarantees better results.
Should you change needles when sewing elastic?
Yes, sewing elastic requires a stretch needle because it accommodates the high elasticity and prevents skipped stitches.
Stretch needles have a special scarf that allows the thread to form properly, ensuring even stitches on elastic.
Using the wrong needle can lead to broken threads and uneven seams, affecting the fit and durability of the swimwear.
Tips for Sewing Elastic in Swimwear
When sewing elastic into swimwear, keep these tips in mind:
- Use a Stretch Needle: Ensures even stitches and prevents thread breakage on highly elastic materials.
- Select the Right Size: 90/14 is recommended for sewing through thick elastic or multiple layers.
- Adjust the Stitch Length: Use a slightly longer stitch to maintain elasticity and prevent thread tension issues.
- Test on Scrap Fabric: Always test on a fabric scrap to adjust tension and stitch length before sewing the final piece.
These adjustments help maintain the elastic’s stretch and comfort, ensuring a snug, durable fit for swimwear.
How often should you change needles when sewing swimwear?
Changing needles regularly is crucial to maintaining stitch quality and preventing fabric damage.
Change the needle every 8-10 hours of sewing or when switching between different fabric weights and layers.
Using a dull needle can cause skipped stitches, uneven seams, and fabric snags. Fresh needles ensure smooth stitching and professional results.
Signs It’s Time to Change Your Needle
- Skipped Stitches: Indicates the needle is dull or bent, affecting stitch formation.
- Puckered Seams: A dull needle can pull the fabric instead of sliding between fibers.
- Snags or Holes: A damaged tip can pierce through delicate swimwear fabric, causing visible defects.
- Thread Breakage: A worn-out needle increases friction, causing the thread to snap.
Regular needle changes prevent these issues and extend the life of your swimwear projects. It also reduces machine wear and tear, maintaining optimal performance.
What brands of needles are best for swimwear?
Several brands offer high-quality needles designed for swimwear fabrics, ensuring reliable performance and professional results.
Top needle brands for swimwear include:
- Schmetz Stretch Needles: Known for durability and consistent stitching on elastic fabrics.
- Organ Ballpoint Needles: Affordable and reliable, suitable for general knits and swimwear linings.
