before I purchased my machine 10 years ago I took a 'certification class' at a shop which was $50- I learned the machine, cleaning, winding bobbins, threading, checking tension, loading the quilt- did a practice quilt...at the end of the class I received a certificate stating I had been (trained) to use the machine- then I had the opportunity to rent time on the machine for $20 an hour- the owner being present to help if there were any problems- after I purchased my machine I too offered the same deal to people who would rather finish their quilt instead of paying me to do it for them- off & on over the years I have had people take advantage of that opportunity...9 times out of 10 after the class and perhaps doing one of their own they decide they would rather just pay me to quilt for them instead- they find out it is actually work. they always still have the opportunity to do their own though-if they choose to do so.
