Me, too, me, too! Want to see it, that is! lol lol Really I do, there are kids all round the world that got baby quilts that were tied by me. There are some in England that were hand quilted, and my own kids had quilts yarn tied. (I'm saving them for my youngest son's children, he's 33 and still living here with us, you think I have a prayer's chance of more grandies or am I keeping clutter??)
The Star Tack sounds like the answer for you! I've used it before for detail and I love the look it gives. It should surely save the day with your wavy fabric, don't you think? Do let us know.
