OK - obviously her mother is not a quilter, that is quite an undertaking. Take a look at Calico Carriage Quilt Designs by Debbie Maddy. I have made several of her "No Y Seams" stars and her patterns are great. Stella's Surprise, No Diamonds in the Sky and Carpenter's/Bali Sky revised all have a similiar though simpler look. With the right fabrics I think you could have a winner!!
