Funny, I always read this as Cheryl's Crown. Anyway. After studying this for awhile, I broke it up into sections. I looked at the photo of Jane's block, to see her seam lines. The Electric Quilt Dear Jane program will not let you break it up this way. I printed out the triangle on paper and paper pieced.
Then, match section to section carefully and sew them together two by two. Here it is, finished. It is close to how the original triangle looks in the quilt.
