I agree with Quiltingcandy. I know how excited I am to start a new quilt....imagine how excited a new quilter would be with a gift card or cash to chose any pattern and fabric. If you live near her, put in your gift the promise of a day of shop hopping to pick it out (with your guidance), and lunch thrown in for good measure. Most 16 year olds have definite tastes and really love to pick their own stuff.
What a wonderful gift idea and what a wonderful memory you can make with and for her.
