My recommendation for a gift is the 6 in by 24 inch ruler along with a pair of embroidery scissors. They are necessary for hand sewing and I use mine all the time at the machine to trim threads.
My most used rulers are the 6 x 24 and the 6.5 x 12. And after that I use the June Taylor thing for cutting strips. Can't think of the name. But if she is going to be a quilter, she will be cutting a lot of strips.
