here are my two cents.
it isn't simply that your quilting is "good enough the way it is." no, no, no. your quilt is beautiful and already has just the right amount of quilting.
in my i'mnotclaimingit'shumblebecauseIKNOWi'mright...aga in...asusual opinion, more quilting would steal attention from all the wonderful piecing and quilting already there.
if you are absolutely, inconsolably convinced it needs more of something to better hightlight the trapunto, then don't add quilting. add stuffing.
