My first suggestion, considering the distance and lack of a mentor on her end, I'd pre-cut whatever I sent and make sure to send easy "1 - 2 - 3" instructions. Given that here are some easy suggestions:
Pillowcases
Totes
Small doll quilt (to tie)
Maybe some 9 patches to begin assembling into quilt blocks to put together at a later date - maybe to bring with her to your house next summer?
