I love your fabric choices. I'd love to know where you got them so I could use them on a quilt for myself. But since she has no further input don't stress about it. Just use your best judgment. This is a gift and since it is a gift it is what you want to do. Obviously she has no idea what is involved in making this quilt. Just include a note with my info and Ill purchase it from her LOL. Don't stress about it isn't quilting suppose to be enjoyabe?
IMO somewhere over time we have lost the concept of a gift. People are less grateful than in the past.
