The LQS here siad she would charge $25.00 for the lesson and $20.00 per hour. You pay from the time you begin loading your quilt till you take it off.
She also said it would take a few hours to do it. But that depends on what you want on it.
This was for the 16 inch. She is now at the 18 inch and it is computerized. I would just have to move the machine back to the start of each line.
