Understanding Knit Fabrics
Top Stitches for Knit Fabrics
1. Stretch Stitch (Lightning Bolt Stitch)
One of the most recommended stitches for knits is the stretch stitch, also known as the lightning bolt stitch. It looks like a slightly slanted zigzag and allows seams to stretch without breaking. This stitch is ideal for areas that experience movement, such as shoulders, side seams, and cuffs.
2. Zigzag Stitch
A classic zigzag stitch is great for beginners working with knits. It can handle the stretch and offers a bit of give, making it perfect for seams that don’t need to be ultra-durable. Adjusting the stitch width and length can help you find the sweet spot for your specific fabric.
3. Overlock (Serger) Stitch
For a professional finish, the overlock or serger stitch is king. It trims the fabric edge while stitching, creating clean, durable, and stretch-friendly seams. This is commonly used in mass production for activewear, undergarments, and knitwear because it’s strong and fast.
4. Twin Needle Stitch (Cover Stitch)
If you’re hemming knit garments, a twin needle stitch gives a polished look with stretch. It mimics the double-row stitch found in most ready-to-wear garments and works well on T-shirt hems and sleeves.
Bonus Tip: Use the Right Thread and Needle
Even the best stitch can fail if the wrong tools are used. Here are two quick tips:
Use polyester or stretch thread – These threads have a bit of give, preventing breakage.
Use a ballpoint or stretch needle – Unlike sharp needles, these glide between the loops of knit fabric instead of piercing them, reducing skipped stitches and damage.
