When you are ready for a quilt for her (and her brothers) check out the pre-cuts from Moda. I wish they had them when I was a beginner. The fabrics are gorgeous, and if you buy charm packs or layer cakes, they go together like magic- just sew the squares together, easy peasy.
The quilt I am making last minute for a graduation present is made out of jelly roll strips, and it's also EASY.
Go to ModaBakeshop.com and scroll through. Some are complex, but there are tons of easy things to make, and they are all beautiful.
good luck
