I have a couple of tips. Put on music, NOT rap or rock, nice soothing music. That will help you get a rhythm.
My friend that recently purchased a sit down machine for quilting complained she was using too much fabric and batting to practice. I told her to use water soluble thread in the bobbin. Practice, practice, practice. then spritz the back and take it apart to do it all over.
This hint was given to me by a quilt shop owner that sold the preprinted panels to practice upon.
