Twin Stretch Needle SINGER 250055603 — size 80/12 twin needle for stretch and knit fabrics

SINGER Twin Stretch Needle 80/12 is a twin sewing needle designed specifically for stretch and knit fabrics. The paired-needle layout produces two parallel stitch lines in a single pass, enabling faster hemming, elastic attachment and decorative topstitching with consistent stitch spacing. The needle geometry and point profile reduce skipped stitches on elastic and knitted materials, helping achieve even, professional-looking seams on garments and home textiles.

Advantages

This twin stretch needle allows simultaneous formation of two parallel rows of stitches, saving time compared with sewing two separate lines. Its size 80/12 is suitable for lightweight to medium-weight stretchy fabrics, while the specialized point and eye help minimize fiber damage and skipped stitches on knit constructions. The twin configuration improves seam appearance for hems, cover-topstitching and attaching elastic, producing uniform results that withstand regular wear and laundering.

Suitable for

• Hemming stretch garments and activewear
• Topstitching and decorative parallel stitching on knits
• Attaching elastic bands to waistbands and cuffs
• Seaming and finishing lightweight to medium-weight knit fabrics

Key specifications

• Needle type: twin (double) needle for stretch fabrics
• Size: 80/12, suitable for lightweight to medium-weight knits
• Configuration: two needles mounted on a single shank for parallel stitch rows
• Point: designed for knit/stretch materials to reduce skipped stitches
• Typical use: hemming, topstitching, attaching elastics

How to use

Install the twin needle into a sewing machine that supports twin needles and matches the 80/12 shank size. Use two spools of thread, one on each spool pin, threading each thread through its respective needle eye following the machine’s twin-needle threading path. Select a stitch suitable for stretch fabrics, such as a narrow zigzag or a stretch-stitch, and set appropriate stitch length and tension. Test on a scrap of the same fabric and adjust settings until stitches lie flat without puckering or loops. Sew slowly at first to ensure both needles pass cleanly through the fabric and the machine feeds evenly.

Usage recommendations

Use quality polyester or stretch thread and a ballpoint or stretch-compatible bobbin thread to preserve fabric elasticity. Avoid using excessive presser-foot pressure on lightweight knits and re-test settings when changing fabric weight or elastic width.
