Lol, bit similar situation haha.. I was such a huge fan of the faber castell watercolour pencils, that I thought everything from them would probably be good quality and easy to use. But maybe I should google a bit more info about the techniques you can use lol.. Did you know you could blend them? I actually got a bit hyper finding that out, as I love the blending of the watercolour pencils. But I have to make some things first I guess, my boyfriend will go nuts, there are several big drawers filled with all kinds of paper and materials lol :)
If you do try, show us please :) have fun!
