Mastering Sewing Knit Fabrics: Techniques and Tips for Successful Projects

Rocking Out Your Knit Fabrics: A No-Sweat Guide to Perfect Sewing

Who says sewing with knit fabrics is a tough nut to crack? With their stretch and comfort, knits are a fantastic choice for your creative projects.But, let's be real, they can be a bit tricky. That's why we're here to help you navigate this seamlessly!

Let's dive into the unique quirks of knit fabric:

Know thy knit!

Before you start sewing, get to know your knit fabric like the back of your hand. Unlike woven fabrics, knits stretch. They come in various types, such as jersey, interlock, rib knit, and more. Invest some time understanding their stretch factors and best uses:

Needles and Thread

Needles

The sewing machine needle is your deal-breaker here. Opt for a:

Ballpoint or Stretch Needle - With rounded tips, they glide between fabric fibers, minimizing snags and runs for a smooth stitch.
Twin or Double Ballpoint Needles - Perfect for hemming, these provide a professional finish with double rows of stitching on top and a zig-zag on the backside, allowing for stretch.

Thread

Choosing the right thread is crucial for durable and flexible seams:

Polyester Thread - Strong and slightly stretchy, ideal for most knits.
Cotton Thread - Softer than polyester but less stretchy, suitable for lighter knits.
Maraflex Thread - Made from 100% Polybutylene Terephthalate, it has elasticity, letting you sew straight stitches on jersey fabric rather than zig-zag stitches.

Sewing Machine Accessories and Settings

Serger or Overlocker

This sewing workhorse is an excellent investment for sewing, especially with knits. By trimming fabric edges and encasing them in thread, it creates strong, flexible seams while preventing fraying and giving a professional finish.

Walking Foot or Dual Feed Foot Attachment

These attachments ensure even feeding of the fabric layers, preventing stretching and shifting. Consider using a walking foot for thicker knits.

Prepping Your Knit Fabric

Pre-wash

Always pre-wash knit fabrics before sewing to account for shrinkage. Knits tend to shrink differently than woven fabrics, so this step is vital for a snug fit.

Pinning

Use fine or rounded pins to avoid creating holes in the fabric. Alternatively, you can use fabric clips, which don't pierce the fabric.

Cutting Tips

Cut precisely with a rotary cutter, ensuring fabric remains flat and uses weights to keep it in place. If possible, cut on a single layer to prevent shifting.

Stitches to Use and Stitch Length

Zig-Zag Stitch

Zig-zag stitches are essential for seams on knit fabrics as they allow for stretch. Adjust width and length as needed, typically assuming a medium width and length.

Using an Overlocker

An overlocker creates durable, stretchy seams. If you don't have one, a zig-zag stitch or stretch stitch on your usual machine will suffice.

Sewing Thicker Knit Fabrics

For thicker knits like double jersey or ponte, use a slightly longer stitch length to accommodate the bulk. Adjust your machine settings to manage thick layers and consider using a walking foot to maintain even feeding.

Finishing Hems and Seams on Knit Garments

For a sleek finish, use a twin needle to hem knit garments. For seams, an overlocker is ideal, but a zig-zag stitch or stretch stitch will work, too. Press seams using a steam iron, but always use a pressing cloth to prevent shine on the fabric.

Tips for Sewing Knit Fabrics

Test on Scraps - Always test your stitch settings on scraps of your fabric before sewing the actual garment.
Start Simple - Start with simple projects, like scarves or headbands, before moving onto more intricate garments.
No Stretching - Let the machine feed fabric naturally to prevent stretching and distortion.
Support the Weight - Ensure fabric is supported as it feeds through the machine to prevent it from pulling and stretching.
Error Correction - If you need to reverse stitches, do so cautiously to avoid damaging the fabric. Use a seam ripper for precision.

When it comes to choosing knit fabrics, pastel polka dot jersey knits, Soon-to-be-Fashionable Knit Fabrics, and comfy sweatshirt knits are popular options.

Choosing the Right Knit Fabric
Pattern Requirements - Choose a fabric that aligns perfectly with the pattern's guidelines concerning weight and stretch.
Desired Outcome - For a clingy, flowy dress, opt for a thinner knit like bamboo jersey. For a structured garment, choose a thicker knit like ponte.
Stretch Factor - Decide whether you need a fabric with two-way (stretches in one direction) or four-way stretch (stretches in both directions) based on the garment's fit flexibility requirements.
