Looking at from your daughter's point of view...
Maybe she was trying to tell you that she's not getting enough attention and subconscientiously she is thinking that the quilting is getting in the way of her time with you.
Just a thought.
I don't remember if you gave her age, but she sounds like a young adult. When I was younger I didn't think things through of what something meant to another person and can remember saying things to my mom that now (at 60) I can't believe I said. When you are gone and all she has is your quilts she may change her tune rather drastically. I'm sure she really wants you to be happy and if quilting makes you happy, keep on doing it.
Also, maybe including her in some aspect of quilting - even if it is just having her come with you while you give some of your quilts to charity and seeing what joy and pleasure it brings to others to receive a quilt, will give her a different view of quilting.
