Go into some specialized store, you can by Fabriano paper size 50x70 and cut it yourself in smaller sizes, also look up for watercolor brands Van Gogh, Schminke or White nights, my faworite. You can buy them in pans so you can make your own palette. You will see the diference once you try things on better materials. If you buy peace by peace it would be easier for wallet :)

Ok, will do. Thanks for the heads up dear!
