In the begining, I had way more ideas than time. Also, I wasn't confident with my abilities and equipment. Since I was working FT, I had more money than time. So anything larger than a throw, I sent to a LA. Pretty soon I discovered my "voice" and no one could give me the same style. Then I discovered art quilts and decided my style had to be from start to finish. The larger quilts lanquished. I purchased a Brother Novelle 1500S. The art quilts got finished and eventually I became confident to do it myself on a domestic machine. Then I acquired a Gammil LA, 12'. Finished up the larger quilts and LA quilted for a few other people. I still do domestic machine quilting on most quilts because my art quilts are small.
Cost, I charge up to 2.5 cents/square inch for panto and upward from there for custom. And a minimum of $50 for the quilting above batting or binding.
All this to say, each person needs to decide their passions, resources, skills, time.
