Yea I think around here a king size quilt would be a min of $200. I prefer to quilt my own as I want it done by me, all me. It certainly takes more time but it is such a great feeling when it is done. I have yet to do a King, but biggest is full size, but my dh said I should make a couple of King sizes for our bed. On the list!
Can't wait to see a pic of your quilt.
