It takes time and know how to set up a machine to do comp.quilting. It actually much more know how than freehand. I do it both ways and comp.quilting is harder on me. It has to be planned to the exact size of the quilt. Borders are separate and hard to do. I think each one has its pros and cons and it comes out even as far as human input is concerned. The most important is what it adds, or sometimes detracts from the quilt. Maybe we should separate those with "stitch regulators" from those of us who learn how to do it on out own.
