I must be denser than their batting because it seems to me that the needle and thread go into the quilt and through the quilt sandwich and then they come back up. What goes down comes back up and then goes back down and so on. Why would stuff beard on the back but not the front?
And why would you want seeds and oil seeping through on the back of the quilt? That sounds not much better than the front?
It's a shame the professional quilter didn't know enough to stop, and great that you found people to undo the damage without damaging the quilt.
Wow, what a lesson in longarming!
