What Treatment?

[Big K]

I just finished a messenger bag based a plan I got from a guy on You Tube. It's a combination of 5-6 veg tan and 5 oz chrome tan. It has a main pouch and a couple of pockets on the front which makes the final seams about 1/2" thick. I neglected to thin the  edges as recommended because I was afraid to screw it up so sewed them full thickness which wasn't a problem until I tried to turn it right side out after finishing the stitching! There was NO possible way to turn it right side with those thick seams and I'm a pretty strong guy. The only way to get it done was to soak it in the sink for a few minutes which softened everything up and it turned out just fine. I then hung it to dry for a couple of days and the leather got pretty stiff......so.........what product/treatment would ya'll recommend to soften the leather? In my opinion, messenger bags should be soft and sort of 'floppy'

Neetsfoot oil and time.

Mix beeswax and neats foot oil into a paste, as thick or thin as toothpaste, and apply liberally all over and after a while buff off the excess with a clean new shoe polish brush and some clean rags
