Personally, I've been a flourisher for a good many years. Although only cards for about 2 years?
What kinds of flourishes do YOU do?
Here's what I do:
Pens/Markers/Pencils/Crayons/Sticks/Drum Sticks
Cards(in case you haven't noticed)
Coins
Finger Rings
AA Batteries
Balls(2-3inches... Normally Bouncy Balls)
As I said, I'm a FLOURISHER... I never said I'm just a CARD flourisher ;)
I do card flourishing....
Ring flourish - Gryphon Roll...
Pen Flourish - Just know v lil...
Coin - Just coin roll..
Balls - hehe... hmmm nah... i dont play with balls... (ok dont start).
But yeah out of all these... Cards are my favourite object to flourish
