Maybe a sewing basket/box/container to store her notions along with some basics like seam ripper, pins, thread, scissors/snips, pincushion, measuring tape, ruler, marking pen, and a charm pack in her favorite colors to get started. Most likely she will want to sew something immediately. It is easy to sew charm squares together and get a small quilt really quickly plus she will learn about seam allowances, how to sew them, and she will get practice for those other projects. Let her guide you into what she wants to sew, if she is like my 9 year old DGD, she knows exactly what she likes and doesn't like!
