I am thinking that she is doing a landscape quilt so she does not need a lot of facial detail. Check this book out - - "When Quilters Gather" by Ruth B. McDowell. Hopefully here is a link to that book on Amazon.com where you can see the front cover and some of the pages from the book. Maybe that will give her some ideas.
