Two things that I found that helped me. First you have to find that sweet spot on your Brother's. You need to be able to hit that speed that is not too slow nor too fast. Watch the speed at which the DSM moves the fabric thru the feet. That is the speed you want to be able to obtain and then match the movement that the DSM would be moving the fabric. Next, don't look at where your needle is at the present, look at least an inch or more to where you want your needle to go to. It is a lot like learning to drive. Remember how much practice we begged for a parent to let us drive ?!?
You will be able to get to the ability to do this with practice, practice and MORE practice. Make some dog beds for a local animal shelters. Dogs will never ever complain about your quilting!!
