As I said, I don't have a scrap of brown so I brought out the paints. I quilted the swirls, then painted three different pieces. The light and milk chocolates are brown on white and the dark is brown on black. I then pieced the various squares and fit them all together. I did have to buy brown thread for the sewing.
I now have scraps of brown left over. What to do with them. Maybe brown and hot pink for Valentines Day.
