I've been watching this thread, and haven't contributed to this point.
As for feathers ... I haven't had any used on any of my quilts yet, whether hand, machine or LAQ. Not that I don't like them, just that I don't think they have been a match for the quilt.
I feel that what is getting lost here is that "each to his/her own". Some like lots of quilting, some don't. Some like a particular quilting design, others like different ones. Some want only hand quilted, others LAQ, others machine, others tied.
And oh yes, I am one of the heathen who piece, but don't quilt. So far I figure there's others there that can do a better job and help my work shine out. Though I am starting to learn on smaller items.
What I appreciate most about this Board is the opportunity to learn. In the case of this thread, to learn why and why not for quilting techniques and options iin an open discussion.
What might be right for me, may not be right for you .... though there's no reason why we can't have a good discussion about all the differences of opinions.
