Bag fairly economical but smooth leaves and unsatisfactory result for me

I prefer when the leaves have already grainy face, allowing to set the colors without drooling. We must therefore take the time to sand a surface of each sheet before using it, it is tedious: as I am pretty lazy I do not redeem it, I prefer to buy already rough leaves ... Incidentally, I have not managed to get after firing flat surface ... To make buttons is a bit annoying. This mark is therefore not suitable to me.
