I have been doing battle with my Derwents and losing - usually resorting to using my watercolour pencils as a dry medium. I just found the Derwents so scratchy and could not get much colour without what seemed like way too much pressure. So I bought a set of 36 Polychromos and I love them! They are as smooth as butter and they have wonderful lightfastness! Almost too good to be true (I just have to live up to them now lol).
These are done with the new Polychromos for a Drawspace Bird ATC swap.I really could see the difference between the cards that I did with the other pencils and the second half after I got the Poly's. Its amazing what a difference a pencil can make.
