Yes Mary, you can do all kinds of quilting on your "regular" machine! As many have said already, it just takes practice. :D
Have you ever seen any of Ricky Tims quilts? I've seen him doing the "fancy" quilting on his regular Bernina! I've also seen quilters at my guild meetings - members & speakers - who have quilted BIG quilts on their 'regular' sized machines.
Personally, I think quilting in the ditch is harder than free-motion stitching :wink: I get stressed trying to stay on those straight lines! LOL
