Is this anything to worry about?

I’m not sure which part of the hide I cut from, will pay better attention next time . I like the way the stretch marks look, just paranoid if it might crack later on . Thanks everyone for you advice !

I have quite a few wrinkly bits of leather in use. The only thing that "broke" was a boot (which I didn't make myself) - it developed a hole at the forefoot (where it bends with each step). I am pretty sure that the briefcase won't see as hard use as these boots, so I wouldn't worry about the wrinkles.

Taking good care of the leather will help (you could maybe give your friend a small pot of Aussie Cream, assuming that is some sort of leather grease?)

Frodo, I do Dip Dye 99% "with the containers and funnel" of everything using Fiebings Pro Dye and love the results too. This piece was too large to fit the container so I spounged the Dye. TomE and Dwight, thanks for the Neatsfoot oil tip and less thread tension. I think I will try that also.After I dyed it and saw what happened I went ahead and cut a new pattern thinking it was ruined. My friend who I was making it for, loved the way it looked so I continued on. Thanks everyone for the tips and taking the  time to help me out.

Thanks Klara,  that is what had me worried. Fiebings makes the "Aussie Cream" .
