I still use pastels, you cant spill them if they are still in stick form
And you CAN make them just as fine as the commercial powders- dont grind them(that makes them chunky) rather use some fine grit sand paper and use that to turn the pastel sticks into a fine dust.
I mix mine with rubbing alcohol since it evaporates quicker than water. And it dires with a nice flat finish, dont forget to put a sealant over the powders though- otherwise they just wipe off like any other dust.
