It's worth noting that I started with a few random sites and built from there.
So I work PR for a club, trust me 4-6 hour shifts of forcing yourself to socialise with passers by can get boring and will turn you in to a sociopath on a miserable day, however our free passes are the size of business cards.
So I have an unlimited supply of cards, learning to throw them accurately would make work more fun, benefit me, benefit the club and look awesome.
This can only go well.
Step 1: You'll need
- a decent supply of uniform business cards, they do get wrecked and until you get better consistency is needed in your cards
- a pretty decent chunk of free time, to get firing cards in a straight line is something you can do overnight, however you forget fast
- a target of some sort, a piece of soft cardboard is good, even card can chip eggshell paint and makes a fair racket on drywall and thin walls
- reasonable wrist strength and loose wrists
If you spend all day typing and mousing this is rather good for your wrist, I haven't tried throwing with my left hand yet since my ambidextry is learned and any new skill takes ages to master compared...
