hexagon in rectangle

I designed this little square to fill the hole between the hexagons joined in the rectangle way. It seams now a little like an italian needle lace and the square continues the design of the hexagon. I like it, but I will also design another one, which has to be completely different, so that is stands out of the design and evidences the hexagons more, perhaps a rose or a threedimensional flower. If somebody of you has a suggestion, it is wellcome.
I must tat it also in one color to see how the design shows up, because it has to be nice also in one color.
