In December 2013 I purchased a longarm machine - Phaff Quilt Artist. My machine is computerized. I don't do very well with freestyle. I generally do my own longarming as most of my quilts and projects are under 54" wide. My computerized longarm machine allows me to pick from thousands of patterns.
If I require longarm services for special quilts or larger quilts, I use Crazy Creek Creations. Nancy is currently not taking new orders but her site is still worth browing through.
I have also listed some references for long arm services on my Links Page. These local businesses provide excellent service.
