You shouldn't push or pull your fabric. I use both hands to guide my fabric through my machine. Watch YouTube videos and get an idea on what you should be doing. Go to
www.craftsy.com and at the top and click on online classes. Then click on quilting and it will take you to a page with many quilting classes. Find the "Craftsy Block of the Month" class...it's free. She has ten classes and teaches you two blocks in each class. The classes are about 43 minutes each. Watch how she quilts. You will get a good idea of how to quilt. I took this class and made a quilt. It's fun and very informative. You will learn so much from Amy Gibson.
