Gramma B. I think you are going to lose your pattern of the butterflies with the hunters star block. what about something like a snow ball one? That way the butterflys would show up better. Or a different star block that has a bigger center that will show off the butterflies. I like to use the Amish Dahlia as a star block. I just make the center square 6 1/2" instead of doing it in pieces like the pattern says to do and don't applique the flower onto it. Or do a disappering 9 patch block with the butterflies as the focus fabric. You can find a lot of different patterns on quilterscache.com. A queen size quilt will take about 6 yards of fabric for the top and the same amt for the backing.
