There is very little talent to crocheting soft toys from a pattern, you basically need to know one stitch and be able to count!
Creating patterns is probably where the skill lies. I’ve only ever made one thing without a pattern, but I prefer not having to think too much, it’s my whilst watching tv activity (I’m incapable of just sitting and watching t.v. without doing something else as well these days). The Pterodactyl was made whilst binge watching Ozark.
Sale wise there are all sorts of hoops to jump through to be able to legally sell plus if you cost the time they take they’d be extortionate. At the moment I just make as gifts.
