With adjustable presser foot pressure, you can also sew very lightweight sheers, and the stainless steel bedplate allows fabrics to glide over the machine with ease. Among the 97 stitch applications is a one-step buttonhole, giving you consistent results every time for projects you'll be proud to say you made yourself. The Top Drop-in Bobbin is not only easy to thread, it's easy to see so you won't run out of bobbin thread in the middle of a seam.
