A domestic sewing machine manufactured by Brother Industries, Ltd., designed for creating two parallel rows of stitching simultaneously. This type of machine typically utilizes two needles attached to a single shaft, allowing for decorative and functional topstitching on garments and other fabric items. An example application includes creating hems on t-shirts or adding decorative stitching to cuffs.
Twin-needle stitching offers several advantages, including increased efficiency due to the doubled stitching speed, and a professional finish often associated with ready-to-wear clothing. Historically, achieving this parallel stitching required specialized industrial machinery, but the introduction of affordable domestic models democratized this technique, making it accessible to home sewists. This accessibility contributes to the enduring popularity of these machines for both hobbyists and small businesses.
