Now you can lift your sewing feet, use the two threads on your left hand (up and down) (assuming you are right-handed), then sew the fabric under your feet and lower your feet. Then you can start sewing. When starting to use, often lift the reverse handle on the right side of the machine to sew 1/2 inch backwards, and then release the back sewing to allow the machine to sew forward again, which can prevent the sex doll from loosening the threads. It’s best to practice sewing this way on some not too thick old fabrics before starting the project. Zipper: When you own a doll, you may often want to sew a zipper on the back of your clothes so that you can place it on the doll more easily. The sewing machine is convenient here. Put the zipper feet on the machine. You can use a pin to fasten the zipper on the back of the garment. If you want to put the zipper into the shirt, please remember that you need 1/2 of a piece of cloth for the zipper because you need to fold the cloth in the sex doll seam. Use enough pins and fasten them along the zipper with the zipper feet. Zip feet can be used on 2 sides. How to do this is usually described, but you can use the zipper foot to sew up to 1/8 inch from the zipper.
