The Schmetz N.75 4mm parallel sewing machine needle is the essential accessory for achieving professional-level finishes on stretch fabrics. Developed by the renowned German brand Schmetz, this double elastic needle allows you to create two perfect parallel seams simultaneously using a conventional domestic sewing machine with a zigzag function. Its technical core features a medium ball point that separates the fibers of delicate knits, such as jersey or cotton knit, without piercing or damaging them, preventing unwanted holes. The special shank and notch design ensures that the needle works extremely close to the hook, effectively preventing skipped stitches even in highly elastic materials. With a 4.0 mm needle spacing and NM 75 size, this model is perfect for sewing and finishing t-shirt hems, necklines, and decorative seams on sportswear or casual wear, making it the ideal choice for seamstresses, tailors, and DIY enthusiasts looking for a flawless overlock finish without needing a dedicated coverstitch machine.
