Sewing your own swimwear can be an exciting and rewarding experience. Not only does it allow you to create unique and perfectly fitting swimsuits, but it also opens up a world of creativity in design and fabric choices. However, working with swimwear fabric requires specific techniques and considerations. This guide will walk you through the process of sewing swimwear fabric, from selecting the right materials to finishing your garment with a professional touch.
The foundation of any great swimsuit lies in the fabric choice. When selecting swimwear fabric, consider the following factors:
The ideal swimwear fabric is typically a blend of nylon and spandex (also known as Lycra). This combination provides the necessary stretch, durability, and quick-drying properties essential for swimwear. Look for fabrics with a composition of about 80% nylon and 20% spandex for optimal performance.
Swimwear fabric should have excellent four-way stretch, meaning it stretches both horizontally and vertically. This ensures comfort and allows the garment to move with the body. Additionally, good recovery is crucial – the fabric should return to its original shape after being stretched.
For added functionality, consider fabrics with built-in UV protection and chlorine resistance. These features will help your swimsuit maintain its color and integrity over time, especially with frequent use in pools or under the sun.
Before you begin sewing, gather the following tools and notions:
A standard sewing machine can work for swimwear, but having one with stretch stitch options is beneficial. If available, a serger (overlock machine) can be incredibly helpful for creating professional-looking seams.
Use stretch or ballpoint needles in sizes 75/11 or 90/14. These needles are designed to glide between the fibers of stretch fabric without causing damage.
Opt for high-quality polyester thread that matches your fabric color. Polyester thread has some stretch and is resistant to chlorine and saltwater.
Swimwear elastic is essential for creating a snug fit around openings. Choose a width appropriate for your pattern, typically ranging from 1/4 inch to 3/8 inch.
Use ballpoint pins or fabric clips to avoid damaging the delicate swimwear fabric.
Proper preparation is key to successful swimwear sewing. Follow these steps:
Although swimwear fabric doesn't typically shrink, pre-washing helps remove any sizing or chemicals that might be present on the fabric. Wash the fabric in cool water with a mild detergent and air dry.
Use sharp scissors or a rotary cutter to cut your fabric. Ensure your pattern pieces are laid out correctly, considering the direction of greatest stretch. Generally, the greatest stretch should go around the body for optimal fit and comfort.
Sewing swimwear requires specific techniques to ensure durability and a professional finish:
Use a narrow zigzag stitch or a specialized stretch stitch if your machine has one. These stitches allow the seams to stretch with the fabric, preventing breakage. Set your stitch length to about 2.5mm and width to 0.5mm for a narrow zigzag.
Swimwear typically requires narrow seam allowances, usually 1/4 inch or 6mm. This helps reduce bulk and allows for better stretch.
Topstitching can add both decorative elements and reinforce seams. Use a twin needle or a coverstitch machine if available for a professional look.
Elastic application is crucial for achieving a snug fit in swimwear. Here's how to do it:
Measure the opening where you'll apply elastic (leg openings, waistband, etc.) and cut the elastic about 10-15% shorter than this measurement. This ensures a snug fit without overstretching the fabric.
â—† Pin or clip the elastic to the wrong side of the fabric, aligning the edges.
â—† Stretch the elastic as you sew, using a zigzag stitch. Ensure you're stretching both the elastic and fabric evenly.
â—† Trim any excess fabric close to the stitching.
â—† Fold the elastic and fabric to the inside and topstitch using a wide zigzag or coverstitch for a clean finish.
Lining adds opacity, support, and comfort to your swimwear. Here's how to incorporate lining:
Use a lightweight, stretchy fabric specifically designed for swimwear lining. It should have similar stretch properties to your main fabric.
â—† Cut lining pieces according to your pattern.
â—† Baste the lining to the main fabric pieces with wrong sides together before constructing the swimsuit.
â—† Treat the lined pieces as one when sewing seams and applying elastic.
The final steps in creating your swimwear include:
For areas that don't require elastic, such as the top edge of a tankini, use a double-folded hem. Press the edge under by 1/4 inch, then again by 3/8 inch, and stitch with a twin needle or coverstitch for a professional finish.
If desired, insert removable cups into the lining of the bust area. Create small openings in the lining to allow for easy removal and replacement of the cups.
Gently press your finished swimwear using a low heat setting. Be cautious with heat-sensitive fabrics and always test on a scrap piece first.
To ensure the longevity of your handmade swimwear:
â—† Rinse in cool water after each use, especially if exposed to chlorine or saltwater.
â—† Hand wash in cool water with a mild detergent.
â—† Avoid wringing or twisting the garment; instead, gently squeeze out excess water.
â—† Lay flat to dry, away from direct sunlight.
â—† Store in a cool, dry place when not in use.
