I have some black fabric from Connecting Threads and the Fusions jelly roll strips. I'm not happy with the color gradations of the JRs for what I had in mind for them but they will be great for this.
I chose a range of blue and pink and added green and yellow. I included a red to bring that color from the center and to tie it into the red/white row. I have a bunch of delicate floral applique patterns that are in loose corner settings so I'll do one in each corner and trail out towards the side centers.
