That's a good idea on the pen! I've been wetting it and that works great for the veg tanned, but the buffalo is too springy. A little pen-mark is probably the ticket.

I also just gave a try on the backing idea too, first with a stiffer piece of leather and then with my beeswax and both made a huge difference. Thanks for all the advice, it's helping me a lot!
