What is the best way to sew an movable arm on a stuffed animal?

To sew a movable arm on a stuffed animal, first create a joint using a safety or button joint for flexibility. Attach the arm to the body by making a small opening in the shoulder area, ensuring the arm can pivot freely. Use strong thread to securely stitch around the joint, allowing enough space for movement. Finally, finish by stitching up any openings and reinforcing the area for durability.
