I have a LOT of tops that need to be quilted. It is just so much more fun to me to piece the tops, but at some point you have to get them quilted. I taught myself to free motion quilt by checking books out of the library and watching tutorials on the computer. I have gotten to the point where I am pretty satisfied with my work. It won't win prizes at the quilt shows, but I don't intend to enter any!
I started out using a quilting foot and stitched in the ditch. This got pretty boring, that is why I changed to free motion. I started out with a loop-de-loop design because I could draw that real easy. then went to things like loop & star and leaves and flowers and water, etc. It really isn't hard unless you want perfection like the prize winners. I can quilt a twin size in about 2 days and a small table topper in a couple of hours. Saves hundreds of dollars! And the project is ALL MINE!
Good luck whichever route you take.
