I just purchased a book that had patterns for "big"prints. It basically shows using such fabrics in rather large pieces with plain sashings. I can see why those fabrics are a challenge. You could use the fabric in fairly large squares or retangles and then just sash it with a solid color that coordinates with everything. Unless the girl is a quilter she would not have a clue and probably love the fabrics. Then you could do a simple meander if you are machine quilting of just an X through each square if you are handquilting. Those busy prints would hide a world of mistakes.
