Your pattern repeat will have some bearing on yardage. You need six lengths of the repeat for hexagon and eight for octagon blocks. I have not made a queen size but would guess it would take at least two sets of repeats. There is little waste. There was black in my fabric. We used black to fill in rows that were not complete and added a black border. If possible you might check your local library for one of the books. One Block Wonder and One Block Wonder Encore are two. There are others. Happy planning.
