I got a private message from the original poster and I answered her but I couldn't post a picture privately so I told her I would answer here with a picture.
I changed the blocks for you to 15" blocks. She has a calculator that helps her with this size blocks. She only wants one border to simplify things.
So, if you use 15" blocks with 5 X 7 layout your quilt will be 75" 105" without borders.
If you add a 6" border to the sides and bottom only, your quilt will be 87" by 111". This is a nice queen with a pillow tuck.
When adding a border to only the sides and bottom, it looks a little funny in a picture but it really looks nice on the bed as you have your quilt blocks showing all the way to your headboard and still get the nice look of a border on the sides and bottom of a quilt. Then I suggest binding in the same fabric as the border.
