I have a used quilting machine, I have quilted for people and I'm always scared something will happen. I pray a lot before quilting someone elses. I don't use pantagrams I don't like them. I just stipple, my machine doesn't have a computer in it and I'm glad just something else to go wrong.
It's a lot of work to quilt for yourself and the public, very demanding. I hope you make the right decision for yourself.
