The quilt looks okay to me. Beats me why people think they have to wash a quilt once it is done, if it is not soiled it don't need washing. Same goes for after they have been used. Some wash a quilt every year, used or not used and kill them. I have been handed quilts to repair that were washed to death and they wonder why.
A batt with cotton and polyester in it will not shrink, so I agree with the other person who said it must have been wool, which in reality is softer than cotton/poly and also comes in different weights. Give her the quilt and if she doesn't like the appearance use it yourself and tell her you will make another.
We don't make mistakes, we have learning experiences.
I never put a quilt in the clothes dryer, you don't know how the fabrics will respond to all that heat either.
To test yarn or a batting, take a small amount and put it in a pie plate or dish, light it, if it is consumed it has polyester in it, if the fire goes out, it is wool.
