You can quilt any size on a regular machine if you want to. Obviously, larger quilts will be more difficult to pin baste and manipulate through the machine depending on how you want it quilted, but it certainly can be done. I wouldn't start out with a queen size if you're just new to quilting, but you'll get there if you want to. I always did mine until the LA trend came around. I am happy to pay to have it done, because I really did not like the process of preparing and quilting a large quilt on my home machine. I love to free motion smaller quilts , wall hangings, table runners, that kind of thing. But sending it out to be quilted now, to me, is a real luxury and a treat!
