I love this. As I sat by my mother's bedside as she was dying, I was considering the block of the month and how I might make it for her. I decided I would ask her caregiver who is a fabricaholic quilter for a bit of her yellow fabric for the yellow brick road as Mom had said she was ready for the trip of a lifetime. I wasn't sure until now how I was going to do the rainbow, but I'll do a variation of yours. Thanks.
