Pros: blend nicely
Be good for big areas
Cons: still messy
Need to spray a fixative.
Difficult to mix colors from the basic set
Difficult to get small details
My personal conclusion:
I still prefer Watercolors
Use pastels for big areas as a background
I know many of you like pan pastels but this is my own experience and conclusions.
It’s always good to try different things and look at the pros and cons.
