Mine does that too - it really takes practice (that is like a four letter word) - then you learn how your machine works and how quick you need to move for curves and straight lines. Sometimes it looks like I am drunk when I am quilting - other times it looks like I know what I am doing (just a lucky day). I look at some longarmers work and I have no idea how they do it - mine looks ok from a distance - but up close you can see my heart beat or hiccup in every stitch so I know how you feel.
