I have always been making stuff - now I decided to film it as I go, so that you can learn from my mistakes.
For some projects, I work with whatever I have laying around in my garage. Others I buy whatever I need to make it.
I have that view on things, that you can study for ages and maybe come out with a perfect product the first time - or as I mostly do, just try something the best you can, and see where it takes you. Maybe it will not be perfect in the first try, but you get something off the hand - and an experience richer.
