I had to laugh seeing 'any Judy Niemeyer quilt' at the top of the list. That would be at the top of my list, too. I admire them when I see them, but haven't yet had an interest in paper piecing and am not drawn to the sharp points. I always admire the effort when I see a cathedral window, too, but so much work! The bargello, DWR and lone star are ones I think about doing down the road.
As for Bonnie Hunter, I enjoy the mystery time very much, and find that the collective energy is a big help in getting these quilts, with their mega numbers of units, completed. The fact that thousands of others are making the same quilt is not a drawback for me, but then, I am a less creative type quilter and doubt I will every improvise a quilt, LOL.
