I can't even tell you the number of times someone has opened a quilt gift from me and then had to give it back so I could finish it. Better that than stressing, hurrying, and making mistakes, which usually ends up with me not really liking something I was very excited about to begin with. Slow down a little, relax, enjoy the process. Give her the unfinished quilt for her birthday, and then when you give it to her finished, it will be like getting a second gift. She'll get to experience the anticipation of something incredible.
