..a way of producing paintings quickly cos I don't have much time (or patience) -   I've tried oils and love messing with acylics (the texture is great) and can do something I'm happy with in a few hours with those, but cos I'm quite allergy-prone I'm now reacting to the chems coming off them (b*gger!), and water colours are too fiddly, and pastels & pencils take me forever and  don't have the same vividness or impact as paints.
  
 So question:   does anyone know anything about techniques with poster paints?
  
 Just thought I'd throw it out there, you never know.    other ideas would be interesting as well !  what does everyone else use if you want to do something in few hours?   cheers!  :)
