Very lovely! I too am making a GFG. I am following a pattern and am making 2" hexies. I will be adding an off white pathway to each rosette. Plus will be adding a green path when connecting the rosettes. The Pattern says I need to make 32 rosettes for a double or 67 for a king size. I will also have three rows of hexies as a border around the quilt. That will make about a 6 inch border Since your rosettes are smaller? Oh my, math is not what I do best! But I can see you need to make more than 32 for a queen size. I guess you should continue to make them, lay them down, side by side until you get the size you want. Good luck! Your quilt will be beautiful!
