Why not take a scrap of fabric and sew it into the shape of a square. Insert a note that says something about how special she is and that the note is good for --- amount in dollars to be spent. Take her to some quilt shops and say that you want to spend some time with her. When she goes to pay, hand her the pouch. She won't know you plan on picking up the bill until she goes to pay....you get to spend time together and give her a gift.
