I think everyone is widely underestimating the cost of hand quilting. I'm sure there are social groups, senior citizen centers, etc. who will hand quilt for one cent per inch. (Please tell me where they are.)
I'm in Dallas and long arm quilting is two cents an inch, and sometimes they add the cost of thread. That doesn't include the backing or batting. That's just computer quilting, not custom quilting. So, you're talking about the $200.00 range for machine quilting.
I've been told that there are deals to be had in small towns. I haven't found them, though. My cousin told me about some one like that, but she was booked for the next 6 weeks and was not taking any additional work until she caught up.
Tell your Aunt the cost of machine quilting and see if she is still interested before you spend a lot of time looking for someone.
