I read your first post and suggested to cut squares instead of fussy cut. Maybe I thought fussy cut would mean you would cut around them and applique. Sometimes my brain doesn't work just right.
I like the idea of using black with your two fabrics.
I agree with others, not too much purple. Whatever you do it will be beautiful.
Maybe look on utube or is it youtube. Suzanne Mac Neil has a video showing how to make a 5 minute block, can be made to look like a cathedral window quilt.
