do you want the logo to be embroidered on a block that you can include in your spacing and design or do you want it to be made like a patch and sewn on to the finished quilt? If you are making the quilt the choice is yours. If the whole quilt is to be in two shades of green and white then the usual design would be having the logo in a medallion block in the middle with a green border, followed by another border in the second shade of green. Then a wide border of white with two more green borders. I would definitely have white on white for a more interesting look. Maybe pararie points instead of a binding.
