I am basically only a handquilter. I do machine quilt small quilts like Linus that will go to children or relatives that don't know how to care for handwork.
I have sent one kingsize quilt to a longarmer. Orginally I was going to have her baste it for me and then do the handquilting myself. When I decided to give it to my step-daughter for her 20th anniversary I had it longarmed. It cost me $165. I still have to bind it. I know my step-daughter will wash it to death. I was not willing to put more than a month's worth of handwork into it for that reason.
