I used to mount a Janome1600P on a New Joy frame, which worked with crib size quilts. Last year I bought a Janome Artistic Design sit-down quilting machine with 18" of quilting space. It came with a table large enough to hold a king-size quilt. It works great; wish I had bought one sooner. I still have some of my quilts done by a professional quilter who uses a Gammill, but for all the charity quilts I make I use the Artistic Design quilter.
