You could use 2 color catchers-I've done it many times. Use the wash cycle a couple of times taking out the old color catchers and adding 2 new ones; but don't dry in between the washes. You could send along washing instructions , or you could explain it is possible the coloring may change a bit after washing, but that is part of the 'vintage' look. When it is washed and dried, the cotton will shrink a bit and with any stitching you have used, the quilt will not have the 'smooth' pressed look as before the first washing. It will have a soft, warm, vintage-y, used, well-loved look and feel. Perfect for giving. She will love it no matter the outcome.
