I am looking for recommendations for a quality conditioner for veg tan leather. I will be using it on natural soft veg tan double shoulder 3-4 oz and natural veg tan double shoulder 8-9 oz tooling leather, both from Weaver. I would like to use an all-natural conditioner free of harsh chemicals. I am brand new to working with leather, so I am a complete novice. Another question is, should I condition the leather before final assembly? I plan to make handbags and other such items.
