@PurpdaBurpPurp: Firstly, I'm not fond of Reeves, myself.
Secondly, Kinkade I've heard can be really good for budget paints.
Thirdly, WATER
Seriously!
Cut open the tubes, take the dried blocks out and put it somewhere else. (Get a small container for 'em of course) And add water.
Watercolours are paints that you can reactivate! Waaaaater~<3
I mean, the palette I use (Royal Talens Van Gogh 18+2 set) I get the 10ml tubes to replace the colours I run out of, and just fill the spot for 'em... and once they dry, just... use 'em like the rest =)
Works perfectly ~<3
