I desinged the pattern myself. The center block is a foundation paper piecing Block, which I designed with Quilt Assistant and Inkscape. The size is 72"x90" This is my second Rainbow Quilt and it shall complement my Rainbow Quilt - Cat -> https://www.craftsy.com/quilting/project/rainbow-quilt-cat/536508. The Quilting is inspired by Christina Cameli's Orange Peel Grid again. Also I split the batting for better Quilting on my sewing machine as suggested in "Machine Quilting in Sections: Strategies for Any Quilt with Marti Michell". I first quilted the Center with the circles and then I attached the rest of the batting and quilted the squares. I sewed the batting back together by hand. I'm not a fan of iron on adhesives. I had the idea myself before I watched the class, but I never tried until my idea was confirmed by this class.
