I am a longarmer. I charge by the sq. inch according to the denseness of the design. I stock 2 battings and charge per sq foot for those. I try not to nickel and dime my customers by adding a lot of extra charges...pressing, re-pinning for borders, etc. If I see that there will be extra work, I just add a little into the charge per sq foot. I only have one Gammill and would NOT even consider renting it! I have been in business for over 5 years and love what I do.
