That was a great lesson for me today. Thank you so much. I shall call the person that presumably does spline caning by default

as I do believe that is what I have. Will make sure before I call but ouch. It is expensive. But worth it on this particular piece. I wouldn't think of putting in a false back.. Not on this at least but it is a good option for other pieces. And thanks for the dog warning

. Won't forget that piece of advice.
