First let me say.... beautiful quilt :thumbup:
I understand your frustration. I went thru the same thing for a very long time.. then I was in WalMart one day and saw a Brother SE400 (sewing/embroidery) machine. Very inexpensive.
It is only a 4 x 4 hoop but I really love it for quilting. I download tons of outline stitches from several embroidery sites and love the outcome! I am fortunate in that I have a large kitchen table to lay out the quilt to support the weight. I have done oversized queens in this method.
