The SINGER® FINISHING TOUCH™ serger saves you time because it sews a seam and seam finish at the same time while trimming away the excess seam allowance. Seams and seam finishes just like you see on store-bought garments are possible thanks to the serger. You can use 3 threads or 4 threads for a variety of stitch combinations. Sew those narrow little hems on napkins with the built-in rolled hem. Use the 4-thread stitch to sew a T-shirt with seams that stretch without popping. Sew a professional seam finish on seam allowances with the 3-thread stitch. Differential Feed allows you to sew super stretchy fabrics without the wavy distortion and sheers without puckering. The Built-in Free Arm makes it possible to sew around small sleeves and cuffs - great for children's clothing and more. You'll love the professional results your serger gives your projects.
