Find a quilt kit that you really like and emulate it with her colors.
This one comes close:
http://www.craftsy.com/supplies/kit/...quilt-kit/1978. Kind of spendy. I don't know your budget.
This one has some blue, but really cute:

This KIT doesn't have the colors, but the pattern would lend itself well to using those 3 colors. Just get a bunch of each and go.

OR-OR-OR
If you have kit sites that you like, ask her to look at some of the kits and tell you some things she likes. Maybe she would go outside of her color scheme for some things she might like.
