I have an Innova 26 and I quilt only for myself but all my quilts are made as gifts for others. I'm basically an amateur in my mind so don't feel confident enough to go professional. Plus I'd worried myself to an early heart attack wondering if I'd damage someone else's quilt while working on it. So many things to think about when working on someone else's hard work, thinks you don't mind if it happens to one of your own. Not to say you're not sad you made a mistake on one of your own but you can live with it as with someone else's, you'd have to worry for so many reasons.
Just my take on the subject.
