Thank you for your response. I like the pronounced grain down then center of the bag. My chèvre Birkin does not have that grain at all. Yours is very pretty! It is certainly a bag fitting for many occasions and a keeper for life.
You can find threads with info and photos of the Chevre “spine”, more pronounced on chevre de coromandel vs Mysore and presumably the new Chamkila. I think there is a thread here called something like Ode to Chevre that you should love reading.
Yes, that is the spine. My K32 is chevre de coromandel (as opposed to Mysore and Chamkila). The spine is usually not so apparent on the other chevre leathers.
