The actual process of screen printing isn't technically difficult. The most difficult part is creating your print designs and acquiring all the equipment that you need to do screen printing.
I first started screen printing a few years ago as I wanted to make t-shirts for selling on Etsy. I watched a ton of YouTube videos on what to do and what equipment I needed to get started. After that, I searched the internet to find a reasonably priced supplier
of screen printing consumables.
Once I had all my equipment, screen printing actually became quite easy. However, if you're not really sure where to start, I would definitely recommend watching some YouTube videos about screen printing before you invest in the equipment as it can cost quite a lot to get all of the supplies. What I will say is that screen printing is really fun and you should definitely try it if you haven't before.
