the photo looks a lot like a selection of layer cakes left square and sewn into strips. if that is what she likes that would be an easy one to construct. then 'quilt as desired' with a really pretty print on the back. it would be reversible that way. as to the 'puffy or ...' do a medium loft, maybe she doesn't know which she would like. she has indicated a style and color she likes and has given you the freedom of pattern choice. it's no fun to stress to much.
