Oooohhh I love the Stonehenge fabric, what a stunning quilt that will make..
I think the best advice I can give for those struggling with fabric choices etc is to relax and breathe, as you see pics of fabric and blocks being posted you will get an idea of color and placement, but above all else don't give up. You are in good company here and we don't let anyone fall by the wayside.
I am rethinking my fabric choices every day
