I love the ease of changing the wide variety of presser feet available for my Singer sewing machine. The slant shank adapter is standard with all the later models. For earlier models, you can purchase one online and have the same ease of presser foot changing.
This video tutorial will have you changing your presser feet like a pro in no time. Whether the foot is screw-on or snap-on, you’ll know how to change it after watching this video.
