Most people believe that a serger is the same as an overlocker. However, there are some subtle differences between the two machines. For starters, a serger typically has more stitch options than an overlocker. Additionally, a serger can create finished seams on all types of fabric, while an overlocker is best suited for knit fabrics. Finally, a serger can be used to create decorative stitches, whereas an overlocker is primarily used for functional stitching.
