Lorraine, this is what Sue said:
Don’t worry that you cut the setting triangles from the green paisley. You have two choices, and it’s up to you:
-- Leave the paisley as the setting triangles; later, if you run out of the green paisley, you can just substitute the large green floral to the extent required.
-- Replace the paisley with the green floral. You should still have enough paisley to do what you need for the rest of the quilt if you use the paisley from the triangles when it is called for in your piecing
