When I look at a professional quilter's website, I assume that the quilts are clients' quilts, not her own personal quilts.
Professional longarmers are a pretty busy bunch. Most lonagrmers who I know rarely have time for doing very many our own. Believe me-- I have a whole closet full of my own quilt tops that are waiting to be quilted. Paying customers come first!!
If the only quilt photos on a professional's website were hers and hers only, I think that there would probably be very few photos.
