First let me extend my condolences for the loss of your grandmother. I don't think it would be selfish of you at all to make something for your family. That being said, since your aunt is making sure you get the scraps maybe you might want to make her something also to let her know you appreciate what she had to go through also. She did go clean the house and I'm betting it wasn't easy. Maybe a lap or throw quilt or even a wall-hanging!
