It's never too late, well... I supposed the day we are put in the ground is the deadline... too dark?
I started leatherworking about a year or so ago at the age of 40. I am disabled and desperately needed something productive to do. My brother bought me a beginners tool kit and a few belt blanks. He was in need of a new belt and I was falling headfirst into a deep, dark depression. Finding purpose in creating pulled me out of that headspace and I started becoming creative again. I will continue to do this until my body gives out, my mind gives out or the money runs out.
Tip: Start small. Each step of the way requires a bit of practice, so begin with something simple to get a feel for it. Just don't wait to get started.
