I've been advertising in stores around here for ages. I have the same waiting list as most longarms do. But instead of waiting for a turn to be quilted, it's waiting for the quilting to finish. I also get 8-10 stitches per inch and am branching out into echo and freehand work. Aside from a small wall hanging, I haven't gotten ANY calls.
Around this area, it seems that long arming is the new "only" way to quilt. It's very frustrating. At the show this year there were only 2 pieces submitted that were hand done and the people going through the show said if they judged it they would have taken off marks for not using different threads and things that are only available for FMQ work. It was ghastly.
I hope you are able to generate some income. I love quilting for other people and hope I'll be able to do more of it someday.
