LOL, was looking for some horsey clip art and found this site...
oooh there are lots! This has some nice ones too! http://www.virtualhorses.com/
hard to find some nice dressage ones that look decent once they are blown up big enough to go on something like a t-shirt tho *sigh*
So many fun and good quotes, my fridge has run out of room for magnets so I'm moving on to T-shirts hehehe, should be set for the rest of my life by the time I'm finished!
