"find the ducky" - the new name for that quilt?
I agree - the quilting is definitely NOT professional looking -
The suggestions to talk to your niece are good - see what she thinks - as OCD as I am - I am tending to agree that the piecing will overshadow the quilting - the top you made is lovely.
And when it is washed and puffed up - the majority of people probably will not look at it all that carefully - what they will see are the colors.
BUT - the people that pointed you in that direction NEED to be SHOWN the work - and perhaps they can talk to the LAer if you aren't willing to.
