Do you mean free motion quilting??? I never use polyester batting but prefer to use cotton battings. They might be easier for you to do when you begin to practice FMQ. You need to find a speed that is comfortable for you that is NOT too fast. After you prep your machine for FMQ, then get the same speed you know and match the same movement that the sewing machine had done. I would take scraps and make small quilts to practice on. Then make them into charity quilts to give to the ASPCA or your local animal shelter. They always need supplies and it will give you time to practice. Never hurts if you can find a LQS to take a class in machine quilting. I took a class from Harriet Hargrave. I had already purchased her book Heirloom Machine Quilting which I refer to when I have a question. Taking her class made all the difference with my quilting ability. Good Luck !!
