Sometimes a person likes a certain fabric for no apparent reason. I tell them if you must have that particular fabric buy it but don't use it in a quilt. Make something else with it.
I have a friend who was making a beautiful Anniversary quilt for her husband of 50 years and the main fabric was gold, burgundy and greens. She wanted to put in a bright orange and I told her it would ruin the beautiful quilt she was making. So she used it in another quilt which worked well.
I sat be honest especially with a friend.
