Ook goedenavond.

Hi,
You can of course start with slinging pebbles, but as most of us had some of our early casts go really wrong, better start with balls.
Tennis balls are often seen as the most useful beginners ammo, but if you want ammo in the same size as the stones you expect to sling later, look for little balls.
I find Action a good place to look for cheap balls.
You will loose many balls when you sling outside.

As for using pebbles, luckily we have a lot of "heide" 5 minutes cycling away and in the evenings it's practically deserted so that makes the perfect training spot. Well, nearly perfect as I recently lost my best stone  , but misfires have been very uncommon  so i'll take my chances.

yours sincerely,
