Looks like you could snowball the patches on two corners (with an added black piping or narrow strip). Then cut diagonally and piece the square in square blocks. Add narrow black sashing. That's how'd do it.
Or for two at once you could do it as a strip quilt and use the opposite side triangles for the back or for another quilt.
