Whether you are an accomplished sewer or a novice, knowing how to sew stretchy fabric is a key skill that will help you with a wealth of sewing projects and save you a lot of nerves.
It’s no secret that sewing with stretchy fabric can be somewhat of a challenge (some people find it downright scary!) Stretch fabrics tend to make up a huge majority of people’s wardrobes. They are comfortable, easy to wear and require minimal care. Learning how to sew elastic fabric will give you the confidence to push your sewing skills. And trust us: it isn’t as hard as you might think.
Types of Stretch Fabrics
Stretch fabric is a generic term for any textile, knitted or woven, that has a greater amount of recovery and stretch than is normally expected. These textiles can be stretch-woven fabrics, single knits, some double knits, and even bias-cut fabrics.
Most elastic fabrics are knits. Jersey fabrics make up a large percentage of this group. The most prominent feature of these fabrics is their 4-way stretch. This means they extend both crosswise and lengthwise. There are some stretch fabrics – usually heavier ones – that only have a 2-way stretch. Therefore, it is vital to make sure you check you are using the right kind of stretchy fabric for your project.
Can I learn how to sew with stretchy fabrics with my home sewing machine?
A common misunderstanding about how to sew with stretchy fabrics is that you need to serger. Overlockers or sergers are wonderful at handling stretch fabrics and creating a polished finish, but are they always necessary? Although a serger can make it quicker to sew with stretchy knits, it is a costly addition to your sewing machine. It is also not imperative for sewing with elastic textiles. A zigzag stitch on a standard sewing machine can be used as an alternative to a serger.
The difficulty some people might find with sewing elastics comes from the amount of stretch that certain fabric might have. It is important to factor in the percentage of stretch in your chosen fabric, and that it matches the pattern you are working with.
Hot tips for working with elastic fabric
By following a few simple tricks and tips, your knowledge of how to sew stretchy fabric will sky rocket. Ensuring the finished seams lie neatly and flat and at the same time don’t break when the garment is used is your endgame.
5 main tricks to knowing how to sew elastic fabric
- Always pre-wash your stretchy fabric–leave it to dry flat for at least a day so that it keeps its shape
- Ensure you have the right fabric for your project or pattern
- Choose the right needle–all stretchy knit fabrics should be sewn with a special needle; either a ballpoint or a stretch needle. A ballpoint needle consists of a rounded tip, which pushes the yarns away when sewing. It avoids damaging knit fabric while cutting and sewing. This contrasts with the usual piercing through and ripping them. Ensure you opt for the right size of needle for your fabric.
- Select the right thread–special threads are not usually required and a regular polyester thread works well as it has a slight amount of stretch.Stay away from cotton thread as it can break when pulled
- Use stitches that will hold the stretch of the fabric–the stitches need to stretch with the fabric, so they don’t pucker and break. If you must sew with a straight stitch, then hold the material taut, but don’t pull it.
TOP TIP: Knowing how to sew stretchy fabric involves knowing how to cut and handle your fabric. The most important thing to remember when cutting your fabric is not to stretch it. We recommend laying it flat on a table or other flat work surface. Don’t let the fabric hang over the edges, as this could stretch it out of place. Some other top tips for knowing how to sew stretchy fabric and how to handle it during the sewing process include:
- Take your pattern and place it on the fabric–to keep your fabric in place, pin it and cut out the patterns with scissors OR use paper weights and a rotary cutter.
- Try to keep pins inside the seam allowance–this avoids opening unwanted holes in the garment
- Take away the curl –some kinds of stretchy fabrics – such as knitted jersey – have edges that tend to curl. This can make it even harder to sew. To reverse the curl, use a starchy spray and press the edges
TOP TIP: Part of understanding how to sew stretchy fabrics is to have patience. It is super important to take your time when sewing these fabrics. Pause occasionally with the needle down, so you can readjust the alignment of the raw edges of the material. Don’t rush it!
5 best stitches and sewing machine settings for sewing stretch fabric
There is a wide variety of stretch stitches available, depending on your sewing machine model. The best stitches to use for sewing stretch fabrics are:
- Narrow zigzag: opt for a very narrow setting with the zigzag, with the stitch length equal to the stitch width
- Overedge stitch:a specialty stitch that locks over the edge of the fabric so it stitches and finishes a seam in one pass
- Straight stretch stitch:this stitch looks like 3 parallel rows of straight stitches
- Twin-needle stitch:this stitch requires a twin needle. The right side of the fabric has 2 parallel rows of stitching. On the wrong side of the fabric, the bobbin thread follows a zigzag pattern
- Try a different presser foot:a dual feed foot or walking foot attachment for your sewing machine are great for helping to stop one layer of material stretching out when sewing. Check the manual of your machine to see which one is compatible
TOP TIP: If you are planning on stitching buttonholes in a stretch fabric, we recommend sewing in the direction of least stretch. This can be difficult with a 4-way stretch fabric, but test all sides to see if one has slightly less give. Stabilizethe wrong side of the fabric first with fusible interfacing. This should give you beautiful and stable buttonholes.
