I'm quite pleased with how the "body" of the sun turned out. I "measured" the middle of the quilt and folded away the outer third of the yellowy centre. Then I got out a dinner plate as stencil, plonked that down, circled it with a quilting pen, got out my embroidering frame and off I took.
Now I need to work on the sun beams. I will do a variation on below's sun with straight and curvey beams alternating and a total of eight beams. All I need to do now is figure out how to make myself a pattern to pin down.
