A couple of months ago I had the opportunity of buying a 12 pan set of professional watercolour paint by Sennelier.
I bought 7 extra pans and put them in the travel tin.
Sennelier paint is not available everywhere in The Netherlands, so I ordered it on Amazon.com.
This is my first set of professional watercolour paint, so I can only tell you that these paints are doing what I expected them to do.
They are particularly suitable for glazing, I have read, and so far this seems to be true.
I am really enjoying them!
I took Sennelier with me on vacation in Switzerland and painted for hours on our balcony with this spectacular view!
Compaired to my Winsor&Newton Cotman watercolour set (a student grade watercolour) the professional Sennelier performs a lot better. Professional watercolour paint has a lot more pigment in it and is a lot stronger.
In time I will buy other professional brands so I can do a comparison.
