I can make stitched circles using fancy machine stitches up to the throat size is radius for nothing. All you need is a drawing pin.
From the pictures . Tape with inches marked from the needle.
Drawing pin positioned at radius distance from needle
Centre of circle on the drawing pin which you tape down and pick stitch and just press foot and go. May need to keep finger on pin to stop centre jumping up.
Move pin for different sizes,
