Loolabell,
If it were my GD, I'd ask her what she would want to make. Then I'd put together a few options for her to choose from.
Once you know what she is 'into' you can decide if you can donate from your stash or prefer to take her on a FART [fabric acquisition road trip] specifically for her project.
The kids I worked with chose to make pillows andmade their own designs. They still have those pillows and love them.
