well, I rather eat dirt than do quilting on my sit down if it is bigger than a table topper. I do have a long arm. Which I did get as a retirement gift to myself. I have straight line quilted up to a queen-sized quilt on a sit down. It was a pain handling all the bulk and weight. I also do not like to do the basting to prepare the quilt. Some people love to quilt at their sit-down. I would advise starting out with a smaller quilt and see how you like it. You could also rent out time on a long arm if you want and see how you like that. I now quilt most of my quilts myself on my longarm but pay if I really want fancy quilting for a special quilt. Works for me. Oh, and you do need to practice if you want to quilt free motion, it takes a while.
