I am slowly improving my skills in FMQ. The best aid I have found for me was fusible quilt batt. I don't have anymore wrinkles on the backs of quilts. A lot of people like the spray basting too. They both seems to stablize the sandwich so you have one less thing to worry about. I find my machinger gloves really helpful too. They aid in moving the fabric under the needle. Do you have a machine with variable speed you can set? That really helps as you can sew at a consistent speed without worrying about going too fast or too slow. Without the particulars of your FMQ problems that is all I can think of. As others have mentioned, there are lots of really good videos on the web. Keep at it and don't give up!
