I took delivery last July but didn't start using it until September (too hot in my quilting room and no AC!)
I quilt for others and myself. Currently my most prolific client is my friend who just took up quilting and she has sent me 8 quilts so far and tells me more are on the way. Thank goodness for her because I am not near as prolific a piecer and would not have gained much experience except for her quilts. I have only quilted 2 of my own and so far I have quilted 4 of hers with one on the rack right now. I also quilted a quilt for a coworker's sister.
I like doing custom work from the front the most. I have done one panto and it was ok but a bit boring working from behind the machine like that. I will, however do more of those but prefer custom freehand from in front.
Edited to add, I am not sure if the market is saturated or not. I hope not as it is my intent to quilt for others more. I think there is always a market for unique work that is exceptional like Green Fairy who is now booked out over a year and Charismah who does such beautiful unique work.
