They include "automatic leather," "automatic overlock," and "automatic single needle" models.• Price & Value: The "price" for these "fully automatic" machines is higher due to their advanced technology, but they offer unparalleled speed and consistency for "automotive," "tailoring," and manufacturing applications.

They offer detailed guides on "how to use" these needles, including "twin stretch" needles for elastic fabrics. Their expertise covers "double needle threading," selecting the correct "presser foot," and understanding the applications and "price" points for different double-needle setups on both domestic and industrial machines.
 
 
WHAT heavy duty lock stitch DOES
 
twin stitch needle / two needle stitch: These terms are synonymous with "twin needle" sewing. A "twin stitch needle" is a single needle shank that holds two needles, allowing a sewing machine to create a "two needle stitch" — two parallel lines of stitching in a single pass. Longsew manufactures industrial machines specifically designed to leverage this technique for speed and consistency.
