i've been doing this for years- i start people out with a (certification class) where they learn the machine- threading, oiling, cleaning, winding bobbins---checking tension---all that- then we load up a practice quilt for them to quilt- the class takes 4 hours (usually) and when they are done they can then rent time for $20 an hour to come in and quilt their own quilts- i do not stand over them while they do this= i help them load and make sure they get going ok-then i usually go to my sewing room to sew- i am available if they have a problem (seldom happens) most of the people who have come in and done this have taken the class- come back and quilted one or two quilts then they seem to decide they would rather pay me to quilt their quilts instead and they go back to just dropping off quilts.. it is always fun to give someone the opportunity to try-
