no problem! When I wanted to learn to freemotion yrs ago I found it so frustrating until I realized my machine just was not made for it. Once I upgraded machines all the problems went away! I also was able to take my workshop I taught and put it into a book. I do a LOT of quilts each year so I never get rusty.
i highly recommend that once you correct your tension you keep quilting every week.. even if it's a small thing.. that way your brain learns this new technique!
